Turbulent mixing of two liquids with an arbitrary law of acceleration

Based on the $(l-v)$ and $(k-\varepsilon)$ models, the present paper examines, both numerically and analytically, the turbulent mixing of two liquids of different densities at the interface between them for various laws of their acceleration, namely, constant, decreasing, increasing, and pulsed ones. The numerical results obtained by these models agree well with each other and with experimental data.
