Abstract

This study presents the effect of magnetic field on the flow and heat transfer of an incompressible Carreau fluid over stretching sheet with uniform suspended dust particle. The relevant governing equations are first simplified under usual boundary layer assumptions and then transformed into ordinary differential equations (ODEs) by similarity transformations. The transformed ordinary nonlinear differential equations are solved numerically by R-K with Shooting Technique. The effects of certain parameters on the dimensionless velocity, temperature profile are presented graphically and also calculated the thermo physical properties of the flow friction factor, Local Nusselt and Sherwood number. The important outcome of this study is magnetic parameter enhances the temperature profile of fluid phase but decreases the velocity of both fluid and dust phase.
