Turbulent flow behaviour through a shock wave turbulent macroscale evolution

The purpose of this study is to describe the behavior of a turbulent field submitted to a shock wave. Experimental results concern velocity and temperature turbulent intensities as well as their time integral scales given by frequency analysis. Besides, classical relations between temperature and velocity fluctuations are examined in this nonequilibrium flow in terms of the fluctuation size. In this flow configuration with an energy supply at low frequency associated largely with production, we are led to formulate a linear type discontinuity model. When the mean flow characteristics are known, this model, built on the Reynolds tensor equation, allows to calculate the turbulent stresses evolution through the shock.
