Simulation of buoyant bubble motion in viscous flows employing lattice Boltzmann and level set methods
Scientia Iranica. International Journal of Science and Technology
Recently, a hybrid Lattice Boltzmann Level Set Method (LBLSM) for two-phase incompressible fluids with large density differences, in cases of negligible or a priori known pressure gradients, has been proposed. In the present work, the mentioned LBLSM method is extended to take into account pressure gradient effects. The lattice Boltzmann method is used for calculating velocities, the interface is captured by the level set function, and the surface tension is replaced by an equivalent bodydoi:10.1016/j.scient.2011.03.018 fatcat:qirgl545zfdhtolvzusctsdfi4
