Research on Gas-Liquid Mixing Method Based on SPH
With the continuous development of computer science and technology, the computational ability of computer has been improved a lot. The particle method based on Lagrangian has become a hot spot in water modeling. In this paper, we first implement a standard multiple-fluid mixing framework based on adaptive hierarchical tree-based neighborhood particle search algorithm and simple boundary correction algorithm. On this basis, the gas-liquid mixing mode is expanded, including soluble gas and insoluble gas. We conducted a series of experiments on the computer to verify the effectiveness of the hybrid method.
