Micro-polar fluid flow over a unique form of vertical stretching sheet: Special emphasis to temperature-dependent properties

Convective micro-polar fluid movement through an impermeable nonlinear stretching sheet with changing thickness is investigated in this research. The governing equations for fluid flow are coupled with nonlinear partial differential equations transformed into ordinary differential equations using the similarity transformation and a numerical second-order finite difference method called the Keller-box scheme. The problem's findings show that microparticle suspensions considerably influence the flow field when different fluid properties are used. We investigate the impact of physical variables on the velocity, microrotation, temperature, skin friction coefficient, and heat transfer rate. The result shows that increasing the micropolar parameter widens the velocity boundary layer while decreasing the thermal boundary layer.
