Turbulent mixing, induced by the Richtmyer-Meshkov instability
Turbulent mixing development induced by passing of shock waves through the interface is studied on the basis of two semi-empirical models, assuming that passing of shock waves through the initial zone of ``roughness'' leads to the instant development of mixing. An expression for the turbulent kinetic energy transferred by the arriving shock wave is given; the value of this energy is determined by a parameter which is equal to the Richardson number. The analytical solutions on the turbulent kinetic energy and evolution of mixing zone with time are given. Comparison of theoretical results with experimental data is made for the impulsive acceleration.
