FINITE ELEMENT SIMULATION OF NONLINEAR MAGNETO-MICROPOLAR STAGNATION POINT FLOW FROM A POROUS STRETCHING SHEET WITH PRESCRIBED SKIN FRICTION
摘要
A mathematical model is developed for the steady magnetohydrodynamic stagnation point thermoconvective boundary layer flow of micropolar fluid over a stretching sheet. An isothermal surface stretched with constant skin friction is considered. A uniform magnetic field is applied perpendicular to the porous stretching sheet. Using similarity transformations, the governing partial differential equations are normalized to a system of nonlinear ordinary differential equations, which are solved numerically with a variational finite element method. The influence of the key physical parameters, namely, buoyancy parameter, magnetic parameter, and transpiration parameter, on the evolution of velocity, microrotation (angular velocity), and temperature function are presented graphically. The local Nusselt number has also been computed for these parameters. Under the limiting cases, the results obtained by using the finite element method are compared with the numerical results available from the literature and excellent correlation is demonstrated. Furthermore, to verify the convergence of the finite element method (FEM) numerical solutions, calculations are conducted with increasing numbers of elements. The study finds applications in magnetic materials processing.
