Abstract

The hydrodynamics field continues to be interested in one of the classic free surface flow problems, the propagation of water waves. In this paper, long-distance water wave propagation is investigated using smoothed particle hydrodynamics (SPH). One of the mesh-free, Lagrangian particle approaches is SPH. The study's goal is to derive a set of parameters appropriate for water wave propagation in a large wave tank. A 24.6 m wave gauge was placed in front of the piston wavemaker, which was used to replicate regular waves. Several SPH parameters are subjected to the sensitive analysis. In this investigation, DualSPHysics version 5.0, an open-source SPH solver, was employed. The findings demonstrated that a parameter with a substantial impact on the accuracy of wave profile is double-precision, particle distance, and coefficient of artificial viscosity.
