Abstract

Abstract: In this paper,a series of particle image velocimetry（PIV） flow field experiments of rarefied gas flow were carried out by setting up a set of experimental apparatus that can adjust the vacuum degree and gradually reduce the system pressure from atmospheric pressure. The system pressure was successively reduced from 101kPa and 90kPa to 10kPa,and PIV experiments were carried out with selected particles under different system pressures to obtain the flow field distribution in the as-measured area. The CFD method was used to simulate the internal flow in the experimental area under atmospheric pressure,and the comparison results show that the numerical simulation results are in good agreement with the flow field structure measured by PIV experiment, thus verifying the reliability and stability of the experiment and numerical simulation. By analyzing the results of PIV experiment：Knudsen number Kn≤0.14 better flow field effect can be obtained by experimental measurement; When 0.14<Kn≤0.29,the flow state in the measured area is still complete but the measured flow field velocity is relatively small; When 0.29<Kn≤0.86,the measured velocity is significantly reduced and the flow pattern is incomplete.

Key words: rarefied gas, PIV, numerical simulation, tracer particle, following performance
