Scale-Resolving Simulations for bubble columns

This seminar presents detailed Euler-Euler Large Eddy Simulation and Scale-Adaptive Simulation of dispersed bubbly flow in different kinds of bubble columns. The main objective is to investigate the potential of these approaches for the prediction of bubbly flows with anisotropic liquid velocity fluctuations. The set of physical models describing the momentum exchange between the phases was chosen according to previous experiences of the authors. Experimental data are used for comparison. It was found that the presented modelling provides very good agreement with experimental data for the mean flow and the liquid velocity fluctuations. The energy spectra obtained from the simulations are presented and compared to the experimental spectra.
