The LIF Measurement of Interaction of Gas Jet Flow with Plane Wall under Low Pressure Condition

Abstract

Discharging gas jets in low-pressure conditions are interesting and important phenomena from an engineering point of view. For example they relate to the gas jet thruster for attitude control of artificial satellite, and gas purging method in the semiconductor technology. The jets, however, deform to the complicated shapes by interacting with solid walls. This paper deals with visualization experiments on the interacting jet and plane wall by applying LIF (Laser Induced Fluorescence) method using an Ar-ion laser. We have obtained a series of jet-wall interacting images at various distances.
