摘要：Combining with a lattice Boltzmann thermal model, a lattice Boltzmann multiphase model with a large density ratio can be extended to describe phase change with mass and heat transferring through the interface. Based on the Stefan boundary condition, the phase change is considered as a change of phase order parameter and is disposed as a source term of the Cahn-Hilliard equation. This hybrid model is applied to simulate the motion and growth of a rising vapor bubble through a uniformly superheated liquid. Meanwhile, the parametric effect on the bubble growth, deformation and rising in the different surface tension forces and kinetic viscosities are also presented.
