Considering the short-range interaction of multi-particles,we conduct a molecular dynamic simulation to Poiseuille flow of electric rheology (ER) fluids based upon the equivalent conduction model.We discover that the period to form the plug zone is greatly shortened and the velocity peak-value of the “respiring” transition increases markedly, compared with the simulation results using dipole model.The formation of the transition zone are clearly explained and we first obtain the three-dimensional evolving graphs of the velocity profile of particles.
