Abstract
For practical application of the numerical wave flume to the coastal engineering problems, considering the computational cost, the open boundary condition is required in order to reproduce the pseudo extension of the flume due to the limited computational domain. Regarding the particle method as one of the numerical wave flume, although it is widely used for the engineering problems thanks to its superiority of tracking the violent free-surface flow, its framework with the open boundary condition is not sufficiently studied particularly for the projection-based particle methods. The particle method is on the basis of the fully Lagrangian method, thus, it is difficult to apply the fixed open boundary condition with flow-in and flow-out of particles. To resolve the problem, in this study, a novel open boundary condition for the projection-based particle methods is developed by using the SPP scheme for the free-surface boundary condition and WPP scheme for the wall boundary condition, which were recently developed with the potential virtual particles. Its good performance for both the inlet boundary condition and outlet boundary condition is shown through some benchmarks.
