Abstract
The motion of small particles in turbulent mixing layer was experimentally studied in order to clarify the dominant factors on particle motion in turbulent gas flow. Spherical glass particles were loaded into the initial point of a two-dimensional air mixing layer. The laser-Doppler anemometry with particle size discrimination enabled to perform measurements of both particles and gas-phase velocities and also particle number density. The results show that the particle dispersion depends strongly on the stokes number, that is, the ratio of the particle relaxation time to the characteristic time scale of the large scale eddies in the mixing layer and overshoot phenomena were observed in the range of the stokes number of about 1.
