| Abstract: | The emulation model for calculating the separation process of piston-type device is presented. The separation characteristics is numerically simulated under two kinds of boundary condition. The main design factors which effect separation velocity and o-verload have been found out. The experimental results show that the method is of high accuracy for the separation characteristics of piston-type device and is of great value for engineering application. |
