ER유체의 유동특성에 관한 실험적 연구

Experimental Investigation on the Flow Characteristics of ER Fluids

Electrorheological fluids (ERF) are suspensions which show an abrupt increase in rheological properties under electric fields. The rheological response is very rapid and reversible when the electric field is imposed and/or removed. Therefore, there are many practical applications using the ERF. The purpose of the present study is to examine the flow characteristics of ERF. First, the microscopic behavior of the ER suspension structure between two fixed parallel-plate brass electrodes applied dc high voltage for the stationary and flow of the ERF was investigated by flow visualization. The electrical and rheological properties of zeolite based ERF were reported.
