... and the gas phase on the top. Taitel and Dukler (1976) sub-divided the stratified flow into stratified-smooth (SS), where the gas liquid interface is smooth, and stratified-wavy (SW), occurring at relatively higher gas rates, at which stable waves form at the interface. Shoham (1982) performed a systematic...

... ABSTRACT: TransAT C M FD (Computational Multi -Fluid Dynamics) code was employed to simulate various types of multiphase flows in horizontal and vertical pipes, under distinct flow regimes. Within the Interface Tracking concept (ITM), use is made of the level set method to track the liquid...

To achieve these results, turbulence in the region close to the interface required the introduction of a law-of-the-wall based correction term in the turbulent energy dissipation equation. Two approaches for the turbulence...
