Homotopy Simulation of Dissipative Micropolar Flow and Heat Transfer from a Two-Dimensional Body with Heat Sink Effect

Non-Newtonian flow from a wedge constitutes fundamental problem in chemical<br /> engineering systems and is relevant to processing of polymers, coating systems, etc. Motivated by such applications, the homotopy analysis method (HAM) was employed to<br obtain semi-analytical solutions for thermal convection boundary layer incompressible micropolar fluid two-dimensional body (wedge). Viscous dissipation<br heat sink effects were included. The non-dimensional value problem<br emerges as system nonlinear coupled ordinary differential equations, virtue of<br suitable coordinate transformations. so-called Falkner-Skan cases are elaborated. Validation HAM achieved with earlier simpler models, well Nakamura finite difference general model. model simulates certain polymeric quite accurately, features rotary motions micro-elements. Primary secondary shear stress, wall couple Nusselt number, microrotation velocity, temperature computed effect vortex viscosity parameter (micropolar rheological), Eckert number (viscous dissipation),<br (pressure gradient) parameter, micro-inertia density, parameter. special Blasius stagnation also addressed. It observed study that thickness both suppressed increasing effect, which beneficial regulation polymer dynamics. Further, strong reverse spin generated viscosity, resulted in<br increase angular momentum thickness. Also, primary skin friction components reduced enhanced substantially greater
