Numerical analysis of entropy generation and induced magnetic field on unsteady stagnation flow with suction/injection

Abstract

The core part of current model is to analyze the entropy generation and 2-dimensional unsteady stagnation flow with suction/injection constraint present in the boundary. Further, the induced magnetic field has applied with this flow model, which is formed by the motion of fluid that conducts electrically. The time-dependent partial differential equations (PDE) of the recent model are first converted to non-linear ordinary differential equations (ODE) using suitable similarity variables. We obtain solutions numerically using inbuilt shooting technic. We demonstrate the results using the graphs, tables and discussed them in detail. It is found that as the injection parameter is responsible for the thinning of the boundary layer, induced magnetic boundary layer; Suction, and unsteady constraints decelerate Bejan number; and the unsteady parameter $(M)$ decelerates the $f^{\prime },g^{\prime }$ profiles and the temperature distributions accelerate by the $M.$
