Particleladen compressible free shear layers
Abstract
The effects of inertia on particle dispersion and flow tracking capability are studied using direct numerical simulations of a twodimensional compressible free shear layers for convective Mach numbers of 0.2, 0.4, and 0.6. It is found that the dispersion of particles show strong sensitivity to the flow inhomogeneity, and that, on average, small particles disperse with the same rate as the fluid particles. It is noted that the slip velocity grows with the ratio of particle response time to the flow time scale, and that the limitation on this ratio is more stringent in the flow visualization based on Mie scattering. The particles with the ratio greater than 0.05 are found to grossly misrepresent the flow features.
