| Abstract: | By using CFD,the software of computational fluid dynamics,Three-dimensional flow in controllable film hydrostatic pressure seal model built with Gambit,was numerical simulated.Based on three-dimensional laminar Navier-Stokes equation and SIMPLE algorithm,the pressure and velocity distribution of the fluid membrane were obtained.The relation between parameters(structure parameters and operation parameters) and seal performance was also obtained.This analysis is helpful to the optimization design of the devic... |
