Impact of Suction/Injection on the Non-Steady Shear-Mode Heat Mass Transfer Flow in Porous Channels

Study’s Excerpt/Novelty This study introduces a comprehensive analysis of heat and mass transfer in porous channels using an implicit finite difference method, providing a detailed examination of the influence of various key parameters. The research offers insights into the interdependencies between suction, chemical reaction, temperature, and their effects on concentration profiles, as well as the role of injection, thermal Grashof number, variable thermal conductivity, and Prandtl number in enhancing velocity and temperature profiles. By employing MATLAB for the numerical analysis, this work contributes to a deeper understanding of flow transport phenomena under complex thermophysical conditions. Full Abstract This study employs an implicit finite difference method to solve the transformed non-dimensional governing equations, highlighting the effects of key parameters on heat and mass transfer in porous channels. In order to demonstrate the behavior of the flow transport phenomena, the numerical results for the velocity, temperature, and concentration profiles are graphically illustrated. Meanwhile, the skin friction, nusselt number, and sherwood number are presented graphically and discussed for a few chosen controlling thermo-physical parameters involved in the problems. It has been noted that while the concentration profile reduces with a rising value in the sequence of suction, chemical reaction, and temperature, the velocity and temperature increase due to increases in injection, thermal grashof number, variable thermal conductivity, and prandtl number. A mat lab software was used for the analysis and obtained all the results of the parameters.
