Abstract: 

Computer simulations of two-phase gas-liquid pipe flow cases have been performed with the commercial code STAR-CD using the VOF method and the results are illustrated in this paper. Computed pressure losses for stratified flow and stratified-wavy flow and time-averaged liquid levels are compared against measured data, showing good agreement with the experimental data. 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 treatment at the gas-liquid interface are briefly exposed and a comparison of the results is presented.
