摘要

The present study analyzes physical fields in a two-dimensional container having a Knudsen number of 0.1, in order to clarify the behavior of unsteady physical fields in reduced pressure systems using the direct simulation Monte Carlo method. It is found that when the temperatures of a pair of wall surfaces facing each other suddenly change to specified values, the induced flow periodically changes the direction with showing a kind of organized motion of molecules. The flow finally disappears, resulting in the heat conduction field with a temperature jump on the wall surfaces. It is also confirmed that when a temperature change of the side walls normal to a pair of walls above-mentioned, which makes a large temperature gradient, is suddenly applied, the thermal creep flow finally appears and subsequently is sustained.
