Burnett Simulations of Gaseous Flows in Transition Regime
Burnett equations with the slip boundary conditions are used to study the three-dimensional gaseous flow in slip and transition regime. The results were first compared with those of DSMC method and good agreements were achieved. The effects of inlet to outlet pressure ratios and Knudsen numbers on flow characteristics were analyzed. The compressible effect increases the pressure nonlinear distribution while the rarefied effect reduces the nonlinear trend. With the same pressure ratio and cross-section area, the flow rate decreases with the increase of aspect ratio.
