Simulation of the Instability of Gas Layer Flow Inside Fluid

Abstract

Gas or vapor layer flow may occur in a number of different physical facilities and devices [1-3], e.g. in a pool with volatile coolant [4,5]. Also, as a stage of drop disintegration through the phase of a film flow [6], etc. In fact, the first two phenomena may occur together in real cases [4,5]. Such liquid gas (vapor) interfaces are prone to different types of instability. The jet’s stability increases in infinite medium by increasing viscosities of jet and medium [7-9]. Instability of thin gas layer between two fluid layers was not reported in the literature yet.
