Effect of Hall current and viscous dissipation on MHD flow over an exponentially accelerated plate with ramped temperature

摘要

A comprehensive numerical analysis is carried out to study the effect of Hall current and viscous dissipation on MHD flow over an exponentially accelerated plate with ramped temperature. The emerging flow governing coupled nonlinear dimensional velocity, energy and concentration equations along with appropriate initial and boundary conditions are transformed into non-dimensional form by using suitable transformations. An efficient, well-validated and versatile numerical Finite element method is engaged to find the solution of resulting dimensionless equations. The variations in flow pattern due to the impact of several controlling parameters are illustrated graphically. The values of skin frictions, Nusselt number and Sherwood number are presented in a tabular form against different parameters. Finally current numerical code is validated with the published literature and a great accordance has been achieved.
