采用格子Boltzmann两相流格式模拟了水平分层两相流中两相速度差引起的界面生长过程。为了验证格子Boltzmann方法产生的界面的有效性，对几个波数分别在二维和三维测量了引起界面失稳和生长的临界速度差。测量结果与开尔文-亥姆霍兹不稳定性理论的分析基本一致。
The interfacial growth of the horizontal stratified two-phase flow, which is caused by the velocity difference between two phases, is simulated by the lattice Boltzmann scheme for two-phase fluid. In order to verify the validity of the interface generated by the lattice Boltzmann method, the critical velocity difference that cause the interfacial instability and growth is measured in 2D and 3D for several wave numbers. The measurement is nearly agreement with the analysis of the Kelvin-Helmholtz instability theory.
