Abstract
An analysis has been performed to study the problem of Electrohydrodynamic flow of a fluid in an ion-drag configuration in a circular cylindrical conduit. The governing equations for this problem are reduced to a nonlinear second-order differential equation. The Galerkin Method, Collocation Method and fourth-order Runge–Kutta numerical method are used to solve this problem. Also, Velocity fields have been computed and shown graphically for various values of physical parameters. The objective of the present work is to investigate the effect of the strength of nonlinearity (α) and the Hartman electric number (Ha) on the velocity field. As an important outcome, Increasing Reynolds numbers leads to reduce velocity and excluded backflow in convergent channel.
