Abstract

The stability of a thin gas layer flow between two fluid layers moving in the same or opposite direction is modeled and simulated numerically. A linear stability is considered for the system using the non-stationary equation array, which consists of the two onedimensional non-stationary equations of a seventh and fourth order. The results of the numerical study showed that the thin gas layer between two liquid layers is unstable to a number of different perturbations of the flow parameters.
