Effects Of Thermophoresis And Brownian Motion On Unsteady Forced Convective Flow Of A Nanofluid Along A Porous Wedge With Variable Suction

Abstract

This paper deals a numerical study of unsteady two-dimensional laminar forced convective hydrodynamic heat and mass transfer flow of a nanofluid along a porous wedge. The model incorporates the effects of thermophoresis and Brownian motion in the presence of variable suction. The dimensionless local similarity equations governing the model are solved by applying Nachtsheim-Swigert shooting iteration technique along with sixth order Runge-Kutta integration scheme. The simulated results are displayed graphically as well as in a tabular form for various values of the model parameters. The obtained numerical results indicate that the flow, temperature and nanoparticles volume fraction are significantly influenced by these parameters. Nanofluids have novel properties those make them potentially useful in many applications in heat and mass transfer. The present model is greatly influenced by the thermophoresis and Brownian motion; thus, can be applied in solving engineering and physical problems related to these mechanisms.
