EFFECTS OF NONLINEAR CONVECTION AND CROSS-DIFFUSION FOR THE FLOW OF DARCY-FORCHHEIMER MODEL MICROPOLAR FLUID WITH CONVECTIVE BOUNDARY CONDITION

摘要

In this article, the collective influence of nonlinear convection and cross-diffusion effects is studied in non-Darcian micropolar fluid flow over an inclined plate with convective thermal boundary condition. The governing equations of the physical model are cast into a sequence of ordinary differential equations by the local nonsimilarity transformation technique. The transformed set of equations is solved numerically by applying a successive linearization method. This significant study addresses the influence of various pertinent parameters on the fluid characteristics and the solutions are discussed through graphs. The influence of the nonlinear density-concentration parameter is additionally outstanding on all the physical characteristics of the present model compared to the nonlinear density-temperature parameter. The cross-diffusion coefficients (Soret and Dufour numbers) have opposite influences on Nusselt and Sherwood numbers. Applications of the present study arise in aerosol technology, space technology, astrophysics, and geophysics, which are related to temperature-concentration-dependent density.
