  • Effect of Turbulence Damping in VOF Simulation of an

    In this paper, a lower turbulence damping factor value is proposed. The new results are evaluated against both the reference bearing chamber experimental data and the previously published numerical data. The results highlight that a transition from shear-driven to gravity-driven flow conditions takes place once the damping factor value is decreased.
