Abstract

An anemometry using tracer particle, such as PIV and LDV, has some errors related to the deviation of particles from the stream, particularly around the large velocity gradient. But the reasonable correcting procedure has never been established. For a notable example, we have investigated the behavior of particle when it passes through a shock wave. In the first report, the effects of particle density and size are clarified by carrying out the simulation with the weak shock theory to the flow field and the BBO equation to the traveling particle. In the present paper, shock wave oscillation and nonuniforme particle size are taken into account, to realize the more exact experimental conditions. The results suggest that the turbulence detected in measurement contains the considerably large amount of errors concerning with the particle property used. In particular, the dispersion of particle diameter is more serious.
