Boundary layer analysis of momentum heat and mass transfer along a stretching wedge in a nanofluid with magnetic field

Abstract

The effect of various dimensionless parameters on boundary layer flow are analysed. The MHD nanofluid flow along a moving stretching wedge surface are considered. The governing partial differential equations are transformed into ordinary differential equations by using the similarity transformation. These ordinary differential equations are numerically solved using fourth order Runge-Kutta method along with shooting technique. The results indicate that the velocity profiles increases with increasing values of pressure gradient parameter β for different situation and also for magnetic parameter M and for stretching parameter λ. The temperature profiles decreases for velocity ratio parameter λ, Brownian motion parameter Nb and Prandtl number Pr but opposite result arises for increasing values of thermoporesis parameter Nt. The concentration decreases with an increase in pressure gradient parameter β, velocity ratio parameter λ, Brownian motion parameter and Lewis number Le, but increases for thermophoresis parameter. Finally, for validity and accuracy the present results are compared with previously published work.
