Effects of thermophoresis on mixed convection flow from a moving vertical plate in a parallel free stream in the presence of thermal radiation

Abstract

This article is focused on the numerical investigation of a steady two-dimensional mixed convection boundary layer flow along a moving semi-infinite vertical plate. The plate is assumed to move with a constant velocity in the direction of the flow. The influences of thermophoresis and the thermal radiation are also included in the analysis. The governing boundary layer equations for the flow, thermal and species concentration fields are transformed into a non-dimensional form by a group of non-similar transformations. The resulting system of differential equations is solved by an implicit finite difference scheme in coupled highly nonlinear partial combination with the quasi-linearization technique. The effects of various parameters on the velocity and species concentration profiles and the wall thermophoretic deposition velocity are presented in terms of graphs. The present results are compared with previously published work and are found to be in excellent agreement.
