Abstract

MR fluid is one of the functional fluids affected by the magnetic. When a magnetic field is applied to MR fluid, MR fluid can change its property because of clustering structure. We measure the ultrasonic propagation property through MR fluid under AC magnetic fields. We use two indexes: ultrasonic velocity change rate and attenuation rate. Based on the experimental results, we analyze the clustering structure in MR fluid.
