Existence of MHD boundary layer hybrid nanofluid flow through a divergent channel with mass suction and injection

Abstract

The aim of this study is to present the existence of two-dimensional steady boundary layer flow of hybrid nanofluid over a diverging channel in the occurrence of an externally applied magnetic field. The walls of the channel are absorbent and subjected to either suction or injection of equivalent amount of the same type of fluid on both the walls. By using appropriate similarity transformations the governing non-linear partial differential equations (PDEs) along with boundary conditions are transformed into a set of non-linear ordinary differential equations (ODEs). The obtained non-linear ODEs with modified boundary conditions are solved using the traditional and competent shooting method. The option of flow under boundary layer approximations in a divergent channel is inspected with the hybrid nanofluid model. The significance of this study is that in the attendance of a magnetic field with appropriate value of magnetic parameter flow separation for hybrid nanofluid flow through a diverging channel can be prohibited. This study discloses that if mass suction exceeds a certain amount then only boundary layer flow is possible and as magnetic parameter increases, the requirement of mass suction for boundary layer flow diminishes.
