Hydrodynamics study of bubbly flow in a top-submerged lance vessel KU Leuven
© 2018 Free surfaces of large bubbles are involved in gas injection into liquid through a top-submerged lance. The Volume of Fluid (VOF) multiphase model is chosen to simulate these flows. However, the selection of an appropriate turbulence model remains a point of discussion. Therefore, three representative turbulence models, namely the Renormalization Group (RNG) k-ε model, the Reynolds Stress model (RSM) and the Large Eddy Simulation (LES) ...
