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.
CFD-Enabled Design Optimization of Natural Convection and Entropy Generation in a Porous Quarter-Circular Cavity Amer Al‐Damook, Saadoon Abdul Hafedh, Fahad S. Alkasmoul, Itimad D. J. Azzawi, Wissam H. Khalil 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.
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.
