The accurate description of the flow behaviour is a key link for the practical application of electrorheological (ER) fluids in fluid control technology. This paper is concerned with an experimental determination of the response performance of ER fluids. A power source control system for ER fluids has been designed to obtain the flow information of the ER fluids in the practical application. The dynamic response of ER fluids in control flow field was experimentally measured. The experimental results show that the response characteristics of ER fluids in control flow field differ from that in rotary shearing flow field. Besides the ER effect, there is a concomitant-effect of ER response called “capture effect”.
