Fluid Flow Characteristics for a Diverging-Converging Magnetohydrodynamic Electric Current Configuration

Abstract

The effects of variations in flow field due to the presence of electromagnetic rotational forces on a transient incompressible and electrically conducting fluid flow are sought. These variations result from interactions between the electric currents with a nonuniform magnetic field. The governing equations are coupled and nonlinear and are discretized using the finite difference technique. Numerical results illustrating the development of secondary flows by the rotational electromagnetic force field are displayed, as well as the effects on the streamline axial velocity profiles by the magnetic pressure number and the flow Reynolds numbers.
