Abstract
In this paper, a numerical wave tank with open relaxation boundaryfor wave simulation is presented under the framework of weakly compressible Smoothed Particle Hydrodynamics (SPH). The open relaxationboundary consists of open boundaries and relaxation particles. A relaxation function is applied for the relaxation particles which are placed between the inflow/outflow zone and the fluid domain. Open particles lie inthe inflow/outflow regions to avoid kernel truncation. The open particlesand relaxation particles can be created and deleted depending on the fluidmotion around the open boundaries, and the properties of these particlescan be obtained from theoretical resolution or by extrapolating withinthe domain. The model is validated by simulating a 2nd Stokes wave andwave runup on a beach. The results demonstrate that the present SPHmodel with open relaxation boundary works well in wave generation andabsorption.
