Abstract:  In order to calculate and adjust the discharge of orifice for magnetorheological fluid, a mathematical model was established through the domain decomposition and analysis of flow field. The local resistance coefficient was revised by numerical simulation. Then, the mathematical model was verified and the influencing factor of discharge was analyzed by the experiment. The results indicate that the discharge of orifice can be calculated accurately by this mathematical model and adjusted effectively by the viscosity of magnetorheological fluid, the length of orifice, the aperture of orifice and the external pressure under certain conditions.

Key words:  magnetorheological fluid, orifice outflow, mathematical model, discharge
