  • Computational Fluid Dynamics–Response Surface Methodology Optimization of Hydrothermal and Entropy Performance in Porous Cassini Oval Annuli
    Itimad D. J. Azzawi, Wissam H. Khalil, Ibrahim K. Alabdaly, Amer Al‐Damook
    Heat Transfer, 2026
    Forced convection and entropy generation through a complex geometry like Cassini oval annuli play a significant role in many applied thermal engineering systems. The novel feature of the present work is a multi‐objective and multi‐response optimal design of the hydrothermal and entropy performance in a porous Cassini oval annular pipe. This approach integrates the response surface methodology (RSM) CFD simulation for evaluating different key design parameters. The variables studied are the inner twisted pipe pitches (0 ≤ P ≤ 1.5), aspect ratios (0.08 ≤ AR ≤ 0.2), porosity (0.1 ≤ ɛ ≤ 0.9), and pore density (5 ≤ PPI ≤ 35) with different Reynolds numbers (50 ≤ Re ≤ 250). These parameters impact heat transfer rate, fluid mixing, and pressure drop. Optimization results indicate that low inner twisted pipe pitch ( p = 0.5), low aspect ratio (AR = 0.08), low pore per inch (PPI = 5), and high porosity ( ɛ = 0.9) are favorable for enhancing hydrothermal performance (NuE = 12.23 and PEC = 3.069) with moderate entropy generation (EG = 0.940). Consequently, this study introduces a useful procedure for optimizing the hydrothermal and thermodynamic performance of forced convection in porous Cassini oval annular pipe cooling systems.
  • Numerical optimization of hydrothermal and thermodynamical performance for metal foam multi-jet impingement cooling
    Wissam H. Khalil, Amer Al-damook, Itimad D. J. Azzawi
    Numerical Heat Transfer Part A Applications, 2026
    A novel porous multi-jet impingement cooling technology since the current conventional cooling technologies are insufficient for thermal engineering devices. This innovative numerical study explores the effect of various metal foam sizes (h/H), jet numbers (n) and wavy jet target plates (C) on the hydrothermal performance and thermodynamical performance at varying Reynolds numbers (Re). The novel results of multi-objective optimum design are a unique aspect of this work by combining the results of RSM with CFD, where low porosity (ε = 0.1), low applied heat flux (Q = 100 × 103 W/m2) and low location jet ratio (LRVin = 0.26) were achieved the aim of the optimum hydrothermal performance (NumP/NumS = 25-30 times and Tb Reduction% = 83.5%-89.5%) and the thermodynamical performance (EG Reduction% = 93%-96% and CoPCarnot = 2.3-6.5 times). Thus, a valuable procedure for the optimal design of the hydrothermal and thermodynamical performance for porous multi-jet impingement cooling is proposed.

    Heat Transfer, 2025
    Natural convection and entropy generation through cavities, including quarter‐circular ones containing porous media, are vital in many thermal engineering application systems. This study introduces a novel approach by investigating the hydrothermal performance of a quarter‐circular cavity using the response surface methodology (RSM) integrated with the computational fluid dynamics (CFD) simulation. The multiobjective optimization design is a novel consideration to enhance heat transfer represented by Nusselt number (Num) and hot wall temperature (Th) with minimization in entropy generation (En) and skin friction coefficient (SFC). These optimizations are considered under varying design parameters, including the cavity inclination angle (0° ≤ θ ≤ 360°), applied heat flux (5 × 103 ≤ Q ≤ 25 × 103) W/m2, aspect ratio (1 ≤ R ≤ 3), porosity (0.15 ≤ ɛ ≤ 0.85), pore per inch (10 ≤ PPI ≤ 30), and cold wall temperature (5°C ≤ Tc ≤ 25°C). The key findings indicate that the optimum design enhances Num by nearly 6.2 times at Q = 5 × 103 W/m2, while reducing Th, En, and SCF by approximately 86.96%, 94.43%, and 99.39%, respectively, as Q = 25 × 103 W/m2 under optimal conditions of R = 1, ɛ = 0.05, PPI = 30, Tc = 5°C, and θ = 0°. The accuracy of RSM in estimating CFD results for Num, Th, En, and SFC is demonstrated by comparing expected and actual results. Thus, this investigation supports the effectiveness of RSM for multiobjective optimization since it improves the thermal performance of porous‐enclosure thermal systems and significantly reduces computation costs while maintaining high data accuracy.
  • RSM and CFD Procedures for Assessing Free Convection and Entropy Generation Performance in a Porous Cassini Oval Annular Pipe
    Ibrahim K. Alabdaly, Itimad D. J. Azzawi, Amer Al‐damook, Wissam H. Khalil
    Heat Transfer, 2025
    Free convection and entropy generation inside a complex annular pipe were vital for different applied thermal engineering systems. The current study investigated the thermal and flow characteristics inside a porous Cassini oval annular pipe, considering response surface methodology (RSM) joint with CFD. The multi‐objective optimum design was a novel consideration to improve heat transfer in terms of Nusselt number (NumR) and heat transfer rate (QR) with a reduction in entropy generation (EnR) and frictional losses (SFCR) under different design parameters, such as aspect ratio (0.08 ≤ AR ≤ 0.2), angular rotation (0° ≤ θ ≤ 90°), porosity (0.15 ≤ ɛ ≤ 0.95), and pore per inch (10 ≤ PPI ≤ 30). The main data indicate that the aim optimum design is achieved in the enhancement of NumR and QR by nearly 23.78 times and the reduction in SCFR by approximately 91.45% with appropriate EnR by about 1.0227 times. This demonstrate the resilience of design's hydrothermal performance under different applied operation temperatures (10 ≤ ΔT ≤ 30). Thus, the multi‐objective optimization function is a useful and novel proposed process for optimizing the hydrothermal and entropy performance of a porous Cassini oval annular pipe under several design and operation parameters.
  • Evaluation of free convection cooling and entropy efficiency in a porous W-shaped cavity using RSM and CFD approaches
    Wissam H. Khalil, Amer Al-damook, Itimad D. J. Azzawi
    Numerical Heat Transfer Part A Applications, 2025
    The cooling and entropy efficiencies of natural convection inside cavities within fully saturated metal foam play a vital role in thermal engineering applications systems. The current study employed response surface methodology (RSM) coupled with ANSYS FLUENT-CFD for a two-dimensional W-shaped cavity, which has not been examined previously. Several effective physical factors were considered, including the aspect ratio (W = h/H = 0, 0.2, 0.4, 0.6 and 0.8) and the applied temperature variation (ΔT = Th − Tc = 10, 20, 30 and 40 K). Additionally, the thermal performance (NumW/NumO and QW/QO) and entropy generation (EGW/EGO) improved under the optimum design of pore per inch (10 ≤ PPI ≤ 30), the number of wave amplitude (1 ≤ n ≤ 3) and aspect ratio (0.2 ≤ W ≤ 0.8) utilizing both RSM and CFD. The results showed that the optimal design of natural convection within a fully saturated metal foam W-shaped cavity at PPI = 10, n = 3 and W = 0.8 resulted in enhancements of approximately 2.875 times for both NumW/NumO and QW/QO while maintaining reasonable EGW/EGO at 1.193 times. Moreover, the novelty aspect of this research lies in the successful achievement of multi-objectives improving NumW/NumO, QW/QO and EGW/EGO by applying the RSM approach in combination with ANSYS FLUENT-CFD. Thus, the optimal working procedure of RSM and CFD is aligned with the desired goals, as the cooling and entropy efficiencies of the porous W-shaped cavity are considered acceptable and satisfactory.
  • Numerical investigation of free convection inside square wavy enclosure using response surface methodology

    Heat Transfer, 2024
    Abstract Free convection is commonly applied in various engineering fields such as solar energy, electronic devices, nuclear energy, and heat exchangers. A computational simulation was used to analyze the natural heat transfer through convection in a wavy cavity with squared shape that was filled with tap water and saturated metal foam to assess the influence of hump configuration (square, triangle, circular, down semicircular, and up semicircular) and magnetic fields (magnetohydrodynamics) on heat transfer rate. The bottom wavy wall of the enclosure exhibits a high temperature ( T h ), whereas the top and side walls maintain a low temperature ( T c ). The present paper will examine how the bottom wall hump number ( N ), aspect ratio ( L ), geometry inclination angle ( θ ), Hartman number ( Ha ), magnetic field intensity inclination angle ( ɤ ) affects the heat transfer rate at various Rayleigh numbers. When the circular hump design is used with specific parameters, including ɛ = 0.85, L = 1.25, N = 4, T c = 0°C, θ = 0°, Ha = 600 and ɤ = 45°, for different Ra values, it leads to increased heat transfer and notable improvements in heat transfer enhancement ( ɸ ) and energy enhancement ( e ). The enhancements were measured at 2.5 times for heat transfer enhancement and 8.9 times for energy enhancement. Moreover, the ideal case of the current study had Ha = 600, L = 1.25, Ra = 30 × 10 3 , and θ = 0° compared to the baseline case. Simulations were accomplished using CFD. The results demonstrate that the primary goal of the research was achieved by optimizing the design, leading to a significant improvement in hydrothermal performance for both ɸ = 2.5 and e = 8.9.
  • Energy, exergy, economic and environmental analysis of a solar air heater integrated with double triangular fins: Experimental investigation
    Ahmed K. Albdoor, Zain Alabdeen H. Obaid, Mohammed Saad Kamel, Itimad D J Azzawi
    International Journal of Thermofluids, 2024
    • The maximum thermal efficiency of a finned solar air heater was 86.4 %. • Exergy efficiency decreased as the airflow rate increased. • The fins improved the thermo-hydraulic performance of the solar air heater. • CO 2 mitigation and carbon credit gains improved using finned solar air heaters. Solar air heaters are considered an important sustainable technology that offers hot air for different applications. This study investigates the effect of using double triangular fins with different arrangements on the performance of solar air heaters. An experimental investigation within the framework of energy, exergy, economic, and environmental analyses was carried out in this study. Four collectors, namely flat plate collector, inline double triangular fins collector, staggered double triangular fins collector, and inclined staggered double triangular collector, were designed and developed to achieve the goal of this investigation. The experiments were conducted on various winter days in Iraq under various airflow rates. All the evaluation parameters were found to be highly sensitive to solar radiation and airflow rate. The results of the finned collectors were compared to those of the flat one and were compared against each other. It was observed that integrating the fins into the collector improved the performance compared to the collector without fins. Moreover, the inclined staggered double triangular collector outperformed the other collectors under all the scenarios. It offered promising performance in terms of daily thermal efficiency, exergy efficiency, thermal enhancement factor, and overall annual energy production, surpassing the flat plate collector by 20.7, 52.7 %, 29.2 %, and 20.7 %, respectively, at respective airflow rates and solar radiation. Furthermore, using such a collector reduced up to 14.3 tons of CO 2 emissions. The findings of this study underscore the benefit of using double triangular fins on the collector and may guide the innovative design of solar air heaters in the future.
  • The optimum computational simulation of MHD natural convection for improved cooling efficiency and entropy performance inside Ϻ-shaped cabinet
    Itimad D. J. Azzawi, Amer Al-damook
    Numerical Heat Transfer Part A Applications, 2024
    The application of natural convection heat transfer within a novel Ϻ-shaped cabinet filled with single-phase pure water/metal foam is investigated numerically. Natural convection is modeled throughout the porous zone using the Local-Thermal-Equilibrium mode and Darcy-Forchheimer-Brinkman law. A novel Ϻ-shaped cabinet with varies Ϻ ratio (0 ≤ Ϻ ≤ 0.8) and temperature difference (10 K ≤ ΔT ≤ 40 K) is applied at a constant porosity of ε = 0.85. Furthermore, the current research is conducted to analyze the response surface methodology (RSM) accompanied by a computational simulation for optimizing the multi-objective function of the M-shaped cabinet in terms of two computed responses: maximizing the Nusselt number ratio (NNR) and minimizing the entropy generation ratio (EGR). The optimization study considers the various pore per inch (10 ≤ PPI ≤ 50), Darcy number (10-9 ≤ Da ≤ 10-1) and uniform magnetic fields (0 ≤ Ha ≤ 100). The results showed that the optimum working conditions consistent with the desired aim are achieved in the maximization of NNR by nearly 20.84 times and the minimization of EGR of 0.895 obtained at Ha = 100, Da = 10-1 and PPI = 30. Thus, the current investigation is a unique application study of CFD and RSM which provides a helpful reference for the optimum design cooling efficiency and entropy performance of a novel Ϻ-shaped cabinet.
  • Experimental and numerical investigation of heat transfer enhancement in double coil heat exchanger
    Ali NAJM, Itimad D.J. AZZAWI, Abdul Mun'em A. KARIM
    Journal of Thermal Engineering, 2024
    In the current work, a substantial research and cost-effective strategy has been conducted to enhance the thermal efficiency of shell and coil heat exchangers, and geometrical modifica-tion is one technique to improve the exchange of thermal energy between two or more fluids. Therefore, experimental and numerical analysis across a shell and single/double coil heat ex-changer at constant temperatures of 36 °C for cold water and 65 °C for hot water are studied. Various coil pitches (baseline pitch, P-2P-P and 2P-P-2P) and mass flow rates (1 L/min for hot water and 2, 4, 6, and 8 L / min for cold water) were studied. The present experimental results for single and double coil heat exchangers were in good agreement with previous research’s numerical study, with an error rate of 9% and 5%, respectively. Moreover, the numerical find-ings revealed that modifying the double coil pitch improves the heat transfer rate by 10% com-pared to a baseline case. Following the encouraging simulation findings, improving the heat exchanger’s performance by utilizing more than one pitch for the same coil is a novel method that has not yet been reported. Therefore, when comparing the modified pitch of a double coil heat exchanger to a conventional coil under the same conditions (400
  • Design and characterizing of blower wind tunnel using experimental and numerical simulation
    Itimad D J Azzawi
    Proceedings of the Institution of Mechanical Engineers Part G Journal of Aerospace Engineering, 2023
    A new subsonic blower wind tunnel design has been studied both numerically and experimentally; it is also referred to as “blower” wind tunnel. This paper is initially aimed to address each sequential stage of the wind tunnel design process. Rather than applying the standard method of modelling solely the flow in the test section, a large-scale CFD model of the whole wind tunnel was employed. The loss of every constituent element was calculated and then all the losses are added up to determine the power needed for the wind tunnel operation which is used as “intake fan” boundary conditions in the CFD model. Then, flow uniformity and turbulent intensity measurements in an empty test section using a pitot static tube and hot wire anemometer (HWA) were introduced to validate the CFD results. The results showed that flow quality was significantly affected by flow conditioners (uniformity devices) (honeycomb and mesh screens) in the settling chamber and wide-angle diffuser. Investigations were also conducted to evaluate the flow deficit in the wake area behind a convex hump model using both HWA and particle image velocimetry PIV. This was additional experimental tests carried out to validate the suitability of the wind tunnel designed for aerodynamic research.
