| Research Abstract |
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.
