FLOW-INDUCED BY TEMPERATURE-GRADIENT ALONG WALL IN RAREFIED-GAS CONTAINER

There is a possibility that flow (thermal creep flow) induced by the t emperature gradient along wall can occur in reduced pressure container s. Simulation of this type of flow is important in material technology , such as chemical vapor deposition or in the design of thermal device s that effectively utilize this phenomenon. The present study attempts to simulate this type of flow by the direct simulation Monte Carlo me thod. As a result, it is demonstrated that thermal creep flows with ma gnitudes of about 10(-2) of the most probable molecular thermal speed are well simulated by using this method.
