Abstract [en]

Multiphase dynamics and its characteristics for two-phase gas-liquid flow have been investigatedby means of advanced numerical simulations. Although important in many engineering applications, methods for robust and accurate simulations for high density and viscosity ratios remainelusive. A comprehensive comparison of two state-of-the-art Computational Multi–Fluid Dynamics (CMFD) codes, Fluent and TransAT, have been performed. The two commonly usedmethods for two–phase flow simulations, namely Volume of Fluid implemented in Fluent andLevel Set implemented in TransAT, could be compared as a result. Significant differences wereobserved between the two flow topologies predicted by the two codes. For the bubbly flow case,a recirculating flow was predicted inside the bubbles by TransAT, meanwhile no significantrecirculation was observed in the solution with Fluent. For the slug flow case a significantdeviation was observed between the results from Fluent and TransAT on the slug formationand frequency. Periodic slug formation was observed with TransAT, in agreement with theexperimental result of Chen et al. [4]. A periodic slug formation was not obtained with Fluent.
