Behavior of turbulized mixtures at the stage of inertial motion for different atwood numbers

Behavior of the turbulized mixtures at the stage of their inertial motion ( with removed acceleration) has been studied. Turbulized mixtures were obtai ned at the contact boundary of two different density fluids as a result of the Rayleigh-Taylor instability (RTI) development, At some instant of time t*, the acceleration sign was changed and conditions for the mixture separa tion were created. Then at the instant of time t**, the acceleration was re moved and the turbulized mixture continued to move under force of inertia. Experiments have been performed at the installations EKAP dagger and SOM.da gger At the stage of inertial motion, the average density distribution of s ubstance in the mixture region and the width of the turbulized mixture regi on have been obtained. The data on the mixture region expansion at the stag e of inertial motion have been obtained as well.
