Outline of Final Research Achievements

In this study, the performance of Knudsen pump which works by the use of thermal induced flow was studied experimentally. The driven force of the pump system presented in this study is thermal creep flow around laminated plates which one surface is black and the other is white. The thermal induced flow is generated by irradiating the infrared lamp to the laminated plates. The system was placed in a glass pipe which was connected to two vessels and irradiated by infrared. It was observed that the pressure ratio of the high pressure vessel and low pressure vessel was about 96% when the temperature difference between the black and white surfaces of the plates were about 40 degrees in the centigrade scale.
