  • Comparative CFD case study on forced convection: Analysis of constant vs variable air properties in channel flow
    Ahmed Hikmet Jassim, Salah M. Salih, Kadhum Hassan Ali
    Open Engineering, 2025
    In this study, a steady-state forced convection heat transfer (HT) of air flow in a two-dimensional channel with a circular cross-section is numerically investigated. The analysis considers two heat sources at uniform temperatures along the lower surface of the mini-channel, with the upper surface remaining adiabatic to facilitate energy exchange. The heat sources are placed at distances L1 = 3.5 m and L2 = 1.5 m on the bottom surface. The finite element method is used to solve momentum-energy equations using Computational fluid dynamics (CFD) software, under constant and variable air properties. HT rates are computed for Reynolds numbers (Re ≤ 2,000) and Prandtl number (Pr = 0.713). The study evaluates the effects of Reynolds number, air thermo-physical properties, and thermal boundary conditions on hydrodynamic and thermal behavior. Results show that changes in the Nusselt number are significantly influenced by Re number, heat source configuration, and air properties. HT rate increases with Reynolds number, highlighting notable differences in centerline temperature, velocity, and conductive heat flux along the lower wall with variable air properties, with a maximum HT rate difference of 14% at T in = 20°C. Pressure also decreases with increasing Re number that shows good agreement between CFD results and empirical Shah equation.

  • Enhancement of cooling process of hot blocks mounted inside a horizontal channel using flexible baffles — Alternative arrangement

    International Journal of Thermofluids, 2024
    In this paper, two heated blocks and three flexible baffles that are alternately placed on the upper and bottom sides of a rectangular channel are used to replicate the transient heat and air movement. The novelty of this research is the use of flexible baffles to destruct the thermal boundary layer with maintaining little pressure drop, and thus reducing the required pumping capacity. The finite thickness blocks are subject to a constant heat flux, while the baffles are very thin and deforms depending on the strength of the flow of coolant (air). Finite element method with arbitrary Lagrangian–Eulerian approach is used for solving such deforming domain problem. The problem is inspected transiently by varying the dimensionless time (τ=0.0 to 10) and two salient parameters which are Reynolds number Re=10−500, and baffle elasticity parameter E=105−108. Results show that the flexibility feature of the baffles contributes not only in directing the coolant towards the hot blocks, but also contributes in reducing the skin friction and pressure drop through the channel. At Re=150, the skin friction and pressure drop of the flexible baffles are 13.2% and 16.5%, respectively lesser than the rigid baffles. The improvement of Nusselt number with flexibility parameter is marginal and within a limited low Reynolds number, where the maximal improvement is about 3.4% at Re=150.
  • Cooling Performance Enhancement of PV Systems: Review
    Mohammed A. Majeed, Salah M. Salih
    Aip Conference Proceedings, 2024
    The most important application of modern technology that produces both thermal and electrical energy concurrently is a photovoltaic/thermal (PV/T) system. Solar radiation incident on the photovoltaic (PV) panel is light photons and heat, by the absorbed light, generated electrical energy, as long as the temperature of the panel increases due to the heat, which negatively influences the performance. Recently, researchers concentrated on improving (PV/T) system performance, by inventing cooling systems that reduce the effect of heat, the most important of which is utilizing air, water, nanofluids, and combined (water+air) or (nanofluid+air) as a cooling medium. Solar air collector with (PV) module called (PV/T) air collector, a solar water collector with (PV) module called (PV/T) water collector, a solar nanofluid collector with (PV) module called (PV-T) nanofluid collector. And (water+air) or (nanofluid+air) solar collector, with (PV) module called (PV/T) combi collector. Furthermore, studies have shown that the integrated cooling method recorded the highest results of the overall efficiency of about (90%).

  • Numerical modelling and investigation of a wavy absorbent solar collector
    Salah M. Salih, Ahmed Hikmet Jassim, Jalal M. Jalil
    Aip Conference Proceedings, 2022
    Numerical modeling based on finite-volume method (FVM) SIMPLE algorithm was established to analyze the 3D-turbulent flow in the wavy two-pass solar collector is proposed. This model is used to analyze and simulate the performance of a V-grooved absorbent collector. The main parameters of an air velocity ranging of(1, 1.5 and 2 ) m/sec, and solar radiation values of(400, 600 and 800)W/m2 are studied. The results presented in terms of temperature and velocity distribution along the system, outlet air temperature, and air temperature rise of the two-pass solar collector’s with wavy absorbent. Also, it is found that the outlet temperature and temperature difference of air is proportionate to the airflow velocity inversely. Further, the temperature difference of air is gained across the wavy absorbent collector. It was approximately 20.7 °C, 19.1 °C and 18.1 °C for 800 W/m2 of heat flux and different air velocities range 1, 1.5 and 2 m/sec, respectively. It was concluded that the collector performance is significantly be influenced by the heat flux and air velocity in the collector.
  • Comparative study of novel solar air heater with and without latent energy storage
    Salah M. Salih, Jalal M. Jalil, Saleh E. Najim
    Journal of Energy Storage, 2020
    Two numerical models are accomplished to predict thermal effectiveness of a novel solar heater with and without paraffin-based on the latent heat storage. The conservation equations with enthalpy transforming method of phase change material (PCM) are analyzed using finite-volume with an explicit scheme. The influence of the main parameters is investigated such as; airflow rate ranging of ( 0.6 ≤ m ˙ a ≤ 1.8 ) kg/min, and heat flux ranging of (625 ≤ Is ≤ 825) W/m2. The results found that the air temperature rise is proportionate to the airflow rate inversely, during the charge/discharge processes. It was concluded that the useful power and the thermal performance are significantly depended upon the solar flux with airflow rate in both models. Moreover, the thermal effectiveness of the collector without and with paraffin was approximately (33.8 – 73.15)%, and (31.3 – 66.77)%, respectively, under the range of the studied parameters. It was noted that the decreased thermal efficiency is (5–7)% with PCM by absorbing the stored energy and releasing it to the system during sunset. To verify the accuracy of experimental and numerical results under the same operating conditions with a mean error of effectiveness with and without PCM was identified of ±6.4% and ± 8.6%, respectively, and the results were acceptable.
