Monte Carlo Simulation of a Gas Transport System Based on Thermal Induced Flow.

In this study, thermal induced flow around a set of thin discs with slits in a straight pipe was investigated using the direct simulation Monte Carlo DSMC method. The surface temperature of one side of each disc was set higher than that of the other side, with the temperature ratio between high and low temperature surfaces (TH/TL) set equal to 1.05. The simulation showed that the pressure rapidly increases before and after the disc, suggesting that the thin disc plays the role of a pump by generating thermal induced flow around the slits in each thin disc.
