In spite of unknown complex dynamics of two-phase flows including gas-liquid interfaces, it is hard to study them with high spatial resolution by numerical computation due to quit less efficiency of parallel computing. By using a large number of GPUs equipped with high computational performance, we have developed a numerical simulator of gas-liquid two-phase flows with high resolution by introducing a new CLSVOF (Coupled Level Set with Volume of Fluid) method, a Pressure Poisson solver of Multi-grid preconditioned BiCGSTAB and IBM (Immersed Boundary Method). In order to get high parallel scalability, an overlapping technique between computation and communication is indispensable.

尽管包括气液界面在内的两相流的复杂动力学未知，但由于并行计算效率较低，很难通过数值计算以高空间分辨率研究它们。通过使用大量具有高计算性能的GPU，我们引入了新的CLSVOF（耦合水平集与流体体积）方法，即压力泊松求解器，开发了高分辨率的气液两相流数值模拟器多重网格预处理 BiCGSTAB 和 IBM（浸入边界法）。为了获得高并行可扩展性，计算和通信之间的重叠技术是必不可少的。
