Mixed Convective Flow in Porous Matrices With Heat Generation/Absorption

ABSTRACT This study presents an in‐depth analysis of mixed convection flow through a porous medium incorporating the effects of internal heat generation and heat absorption. The novelty of this study lies in the combined evaluation of localized heat sources, chemical reactivity, and magnetohydrodynamic (MHD) influences within a single porous configuration—an approach rarely addressed collectively in prior work. The governing equations, expressed as nonlinear, dimensionless ordinary differential forms, are solved using the regular perturbation method. The results reveal the combined influence of these factors on velocity, temperature, and concentration profiles, offering insights applicable to engineering applications such as advanced cooling systems, filtration processes, fuel cell design, and biomedical devices like blood purification units.
