Heat transfer analysis of micro-polar fluid flow over an expanding/contracting permeable plane wall

This research examines the stagnation-point flow of a micropolar fluid flowing past a porous, stretching or contracting flat plate, incorporating velocity and thermal slip boundary conditions. The governing partial differential equations are converted into corresponding ordinary differential equations by employing similarity transformations, which are subsequently evaluated numerically by applying a shooting technique. The influence of principal physical parameters on the distributions of velocity, microrotation, and temperature is explored and depicted through graphical representations. Furthermore, computed results for the wall shear stress coefficient and the heat transfer rate across a range of parameter values are provided in tabular format.
