“…The research results recorded that the thickness of the boundary layer decreases in the presence of the porous material, which leads to an improvement in the heat transfer coefficient in the tube. Amir S. Dawood and Osama Basil Hmood [4] The research includes a numerical simulation of convective heat transfer in a rectangular space filled with porous medium, the walls of the space are exposed to a constant temperature. The governing equations (conservation of mass, conservation of momentum, conservation of energy) of the fluid flow have been solved using the method of finite differences for the range of the Rayleigh number (0 -500).…”

In recent years various modern improvements have been used to raise the performance of heat systems in various engineering and industrial applications. One of these improvements is the use of porous material. This research focuses on conducting a theoretical study (numerical simulation) via forced convection heat transfer of three channels of various cross-sections (square, rectangular, and triangular) with an equal hydraulic diameter of (0.15 m) with glass spheres filled of a diameter (0.012 m) as a porous martial. The lower surface of the test section is subjected to a uniform heat flux along the fluid flow of (5000 W/m 2 ), while the upper surface is thermally insulated. The type of model used in this study (k-epsilon turbulent model) to simulate and analyze fluid flow inside three channels. This study aims to enhance the thermal properties of the fluid (water) and study its effect on the distribution of temperature, velocity, and pressure, respectively. The results showed that the channel with a triangular cross-section gives the highest distribution of temperature and pressure compared to the rest, and therefore it is considered the optimal design for the channels.

“…Analyzing the results revealed that velocity reduces as the Hartman number increases while it increases when the values of mass Grashof numbers and thermal are increased. Danwood and Hmood (2006) investigated the effects of unvarying and free convective flow across a permeable media all over an isothermal body. The results proved that the Nu number is a powerful function of the so-called modified Rayleigh number.…”

This study investigated MHD flow in a porous medium across parallel plates with mass transfer in a rotating system. The governing equation of momentum were non-dimensionalised on velocity and concentration gradient. The resulting equations were then transformed using FD to fit some algebraic matrices solved by computer software (MATLAB). The end equations were analysed for velocity and concentration profile. The numerical data on concentration and velocity profile were recorded and presented graphically for interpretation and discussed. Some of the results revealed that velocity decreases when magnetic parameter and Grashof number increases. The knowledge obtained from this study can be applied in real life situations such as engineering and industries such as polymer processing.
