考虑多颗粒近程相互作用，利用等效平板电导模型，由分子动力学方法模拟了电流变液泊肃叶流动行为.研究结果表明在外电场作用下，流动流体形成柱塞区的时间比由偶极子模型所得结果大为缩短，呼吸式跃迁峰值也有很大提高.依据颗粒在接触区的相互作用解释了跃迁区的形成.模拟出三维颗粒运动速度剖面和颗粒结构状态演化过程.

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.
