MHD Stagnation-Point Flow and Heat Transfer Over an Exponentially Stretching/Shrinking Vertical Sheet in a Micropolar Fluid with a Buoyancy Effect

Abstract

The MHD stagnation point flow and heat transfer in a micropolar fluid over an exponentially vertical stretching/shrinking sheet are investigated in the presence of convective boundary conditions in the current work. The buoyancy effect, also known as mixed convection, is also taken into account. Several researchers are conducting research on the fluid in the current state of mixed convection. To convert the governing equations from a system of partial differential equations to ordinary di fferential equations, similarity variables were used. The modified equations are then numerically solved in MATLAB usingBVP4c. There is a lot of agreement when compared to previous findings. Contradictory phenomena are observed between Micropolar and mixed convection for fluid velocity, angular velocity and temperature distribution profiles. The significant variables' characteristics are graphically presented, and the numerical results are tabulated.
