NONEQUILIBRIUM AEROSOL FLOW IN A SUPERSONIC WIND TUNNEL
RÉSUMÉ
The article is dedicated to increasing the informational content of the nonintrusive diagnostic of fluid flows by analyzing the behavior of particles introduced into it. Corrections to the difference between the tracer particle velocity and the carrying flow velocity are developed. A criterion for identification of two-phase flow high-velocity nonequilibrium areas is proposed. Methods to solve the inverse problems of determination of the flow parameters according to optical measurements data are offered, and the stability investigation results of the respective solutions are given. Numerical algorithms of determination of pressure, density and temperature fields of a non-equilibrium flow using the velocity field of the particles moving in it are created. The results of recovery of gasdynamic parameters recovered in a supersonic high-gradient flow through the velocity fields of the particles introduced into it are given.
