Abstract

The Bingham-plasticmodel has been widely used to predict the post-yield behavior of Electro-Rheological(ER) and Magneto-Rheological(MR) fluids. However, as the plastic viscosity is not constant under conditions of different flow velocity and applied field (Electric/Magnitude), the phenomenon of shear thinning or shear thickening exists in the flow of ER/MR fluids. At this condition, the Bingham-plastic may not be an accurate model to predict the behavior of ER/MR fluids.In this study, the equations of motion of the MR fluids based on parallel plates and annulus duct models has been established, and the general solutions has been obtained based on the Herschel-Buckley model. The analysis of the impacts of the external magnetic field strength applying on the MR fluid has also been conducted. Therelated velocity profile, flow rate curves have been presented in the numerical example to verify the validity of the proposed methodologies.
