Description
Summary:The effects of thermophoresis and MHD on Darcy-Forchheimer nanofluid mixed convection flow with heat and mass transfer from a vertical flat plate embedded in a saturated porous medium is studied by taking into the influence of radiation. The fluid is considered in a grey medium and the Rosseland approximation is used to describe the radiative heat flux in the energy equation. A similarity solution for the transformed governing equations is obtained. The coupled non-linear ordinary equations are linearized by using Quasi-linearization technique. The governing coupled ordinary differential equations are being solved by employing an implicit finite difference scheme. Numerical computations are carried out for the non dimensional physical parameters. The results are analyzed for the effect of different physical parameters, such as radiation R, mixed convection parameter Rax/Pex, buoyancy ratio N, inertia parameter Λ, magnetic field parameter Ha, Prandtl number Pr, Brownian motion parameter Nb, thermophoresis parameter Nt and Lewis number Le.
