212 Experimental Analysis on Flow Structure and Flow Control Characteristics of MR Fluid in a Pressure Mode under Magnetic Filed(2)

Abstract

Experimental analysis on the cluster formation of MR fluid and rheological properties under the magnetic field are carried out. Through the measurement of ultrasonic propagation velocity in MR fluid, the cluster behavior in pressure-driven flow is clarified in detail. Finally, the flow control characteristics of MR fluid in a rectangular channel are evaluated to provide the fundamental data for the design of the advanced MR valve system.
