On the interaction between bubbles and the free surface with high density ratio 3D lattice Boltzmann method

On the interaction between bubbles and the free surface with high density ratio 3D lattice Boltzmann method

ABSTRACT: The bubbles rise up and burst at the free surface is a complex two-phase process. A free energy lattice Boltzmann method (LBM) model is adopted in this paper to study this phenomenon. The interface capturing technique [Zheng et al., 2006] is used to deal with the high density ratio problem...
