A Numerical Study of Viscous Dissipative Transport of Viscoplastic Fluid Influenced by Induced Magnetic Field

摘要

The present work is a detailed study of a steady two-dimensional stagnation point flow of non-Newtonian fluid toward a linear stretching surface with induced magnetic field. Problem development is accomplished in existence of convective boundary condition. Nonlinear flow analysis is computed with the help of shooting algorithm. Physical characteristics of pertinent parameters have been analyzed through graphs and tables. The main emphasis of the present study is to analyze the impact of induced magnetic field with incorporation of stretching ratio parameter (when A1 and A1) on fluid velocity and temperature profiles. Magnetic and fluid constraints contribute in lowering mass boundary layer thickness for fixed value of stretching ratio parameter. However, magnetic Prandtl number reciprocal, fluid and magnetic parameters contributed in enhancing induced magnetic profile for a fixed value of stretching ratio parameter. Comparison with available results in the literature in limiting sense is achieved. Moreover, heat flux has opposite effects for magnetic and fluid parameters, but has same effects for magnetic Prandtl number.
