Numerical simulation for MHD flow of Powell Eyring nanofluid with heterogeneous–homogeneous reactions, Arrhenius energy over a variable thickness stretching surface

Abstract

The paper deals with the viscous incompressible flow of Powell Eyring type nanofluid over a variable thicker stretching surface induced by heterogeneous-homogeneous reaction and Arrhenius activating energy in a porous medium. Brownian motion and thermophoresis effect also considered to define flow regime. Boundary layer approximations of the governed flow are described by the partial differential equations which are laidback to handle by reducing them into coupled nonlinear ordinary differential equations. A MATLAB package BVP 4c is used to simulate the equations very contentedly to describe the behavior of several parameters graphically. Impact of several governing parameters are discussed. Rationality of the resolution is scrutinized by the comparison with previous literature in Tables 1 and 2. Numerical values of the Nusselt number and Sherwood parameters are discussed in Table 3. velocity profile diminishes for magnetic parameter, variable thickness, first slip and second slip parameters. while uplifted for mixed convection parameter. Temperature profile tumbling for Prandtl number and uplifted for radiation parameter, Brownian motion, thermophoretic effects, Grashof number and Magnetic field effects. Concentration profile declines for Schmidt number, chemical species and homogeneous heterogenous parameters.
