Abstract
Considering the mass effect and short-range interaction of multi-particles in electrorheological (ER) fluids, the structure evolution in Poiseuille flow was simulated by means of the equivalent plate conduction model and the molecular dynamics method. It was seen that the velocity peak value in the transition zone decreases obviously with particle's mass, time and width to form the plug zone increase, which was compared with those not considering the particle's mass. The experiment to observe the structure evolution of ER fluids was also devised. The structure evolution observed in experiment complies with the simulation fundamentally. Moreover, the hypothesis that there is no slip between particles and electrodes in contact zone was also testified by our experiment.
