Effect of Heat Transfer on Radiative MHD Micropolar Fluid Flow over a Stretching Inclined Sheet in the Presence of Chemical Reaction and Heat Sink/Source

This study examines the steady, two-dimensional magnetohydrodynamic (MHD) boundary-layer flow and heat transfer of a micropolar fluid over an exponentially stretching inclined sheet. The analysis incorporates the effects of viscous dissipation, Joule heating, thermal radiation, a porous medium, a chemical reaction, a heat source/sink, and velocity slip. The nonlinear partial differential equations governing the flow are converted into ordinary differential equations through similarity transformations and solved numerically using MATLAB’s bvp4c solver. The numerical solution demonstrates reliable convergence and accuracy, confirmed through comparison with published benchmark data. The numerical results for velocity, angular velocity, temperature, and concentration are presented graphically, and the influence of various parameters, including the Chemical Reaction Parameter, Porosity Parameter, Eckert Number, Thermal Radiation Parameter, and heat source parameter, is analyzed. Results indicate that Eckert number, thermal radiation parameter, and chemical reaction parameter significantly elevate the thermal boundary layer thickness. Conversely, higher porosity parameters reduce temperature and concentration profiles. Further, skin friction, Nusselt number, and Sherwood number demonstrate clear sensitivity to melting effects. Findings from this work provide insights relevant to industrial processes involving polymer extrusion, thermal insulation systems, porous media transport, and heat-assisted chemical reactors.
