摘要：A lattice Boltzmann model for two-phase flow with large density ratio in body-fitted coordinates is proposed and validated through a series of comparison with analytical and published results with good agreement. A single bubble sliding over a curved surface and rising in a channel for different Eotvos numbers is simulated. The results show that during its sliding process, the surface makes the bubble experience large deformation, with both horizontal and vertical velocities fluctuating. As the bubble continues to move, it departs from the surface and starts to rise freely in the channel. With Eotvos number increases, the departure angle decreases.
