Combined effect of thermophoresis and Brownian motion on MHD mixed convective flow over an inclined stretching surface with radiation and chemical reaction

Abstract

A study has been carried for an incompressible electrically conducting, viscous fluid past a continuously stretching surface in the presence of thermal radiation, viscous dissipation and first-order chemical reaction with thermophoresis and Brownian motion. An inclined uniform magnetic field is applied to the fluid flow region. The governing coupled partial differential equations (PDEs) that describe the model are transformed into a set of nonlinear ordinary differential equations (ODEs) by applying similarity analysis. The resultant nonlinear coupled ODEs are computed numerically in MATLAB software using the boundary value problem solver (BVP4C). The effects of various physical parameters have been examined graphically on velocity, concentration and temperature distribution. The comparison has been made from the previously published work, and there is a good agreement with that. These results can be helpful in geothermal engineering, energy conversation and disposal of nuclear waste material. Moreover, this combined effect can also help biologists to study biological macromolecules such as genomic-length DNA and HIV in the microchannel.
