In this paper, the influence of density ratio on the atomization of liquid droplets under highly unstable conditions is numerically investigated with a coupled volume-of-fluid and level-set method. By employing the adaptive mesh refinement technique, the computational cost is significantly reduced and good agreements with experimental measurements on both the morphology and trajectory of droplets...
The Lattice Boltzmann method (LBM) has proven to be a promising approach in handling multiphase flow problems. In the most widely applied pseudopotential-based LBM multiphase models, multiphase effects can be added in the form of forces, which is further divided into two aspects of force incorporation scheme and force expression. However, the effect of both aspects on coexistence densities and spurious...
