| Abstract: | A linearized stability analysis of the nonzero pressure gradient Couette flow of ER fluid has been performed. The constructive equation used here was established by Wineman and Rajagopal. After numerical evaluation, it comes that any motions of the boundary wall are shown to have a stabilizing effect. With the applied extra electric field, the effect of ERF can also enhance the stability. |
