Abstract

The paper presents the study of velocity profiles in a hydromagnetic flow of Boussinesq-Stokes suspension over an exponentially stretching impermeable sheet. The basic equations governing the flow are in the form of partial differential equations. The equations have been transformed to nonlinear ordinary differential equation by applying a suitable local similarity transformation. The solution of the transformed equation is obtained by using differential transform method (DTM) with assistance from the Newton-Raphson method in obtaining the unknown initial values. The solution is obtained as a power series with assured convergence. The effects of local Chandrasekhar number and couple stress parameter on velocity profiles are studied. The findings of the study are represented graphically.
