Sensitivity analysis of SPH parameters for long-distance water wave propagation

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