The molecular dynamic simulations in Poiseulli flows of ERF

We investigate the movement of particles in ERF that is under Poiseulli flo w by virtue of molecular dynamic simulations. The velocity profile of parti cles we simulated is divided into two zones. The zone near the electrodes w here the par tide velocity profile changes periodically like breathing type , we called it the transition zone. The zone between the two electrodes whe re particles move smoothly as a plug, we called it the plug zone. In additi on, we also simulate the relationship between volume flow rate and relative pressure gradient. We then analyze the factors that influence the volume f low rate, critical electric field, critical pressure gradient and the respo nse time of shutting flow respectively.
