Abstract
The transient flow that follows an instantaneous change of yield stress of a magnetorheological(MR) fluid in round tubes is analyzed by an exact analytical method. The time required to establish steady flow of MR fluids after a sudden yield stress change as well as for combinations of step-change in the pressure gradient and yield stress is determined.
