Abstract Smoothed particle hydrodynamics (SPH) was presented for 2D free surface flows based on the assumption that the fluid was treated as weakly compressible. The normalized quintic spline function was used as SPH kernel function. The flow pressure was obtained by the solution of equation of state. The threestep method equipped with variable time steps was employed in explicit time stepping. A link list algorithm served as an efficient nearest neighboring particles searching and dynamic particles were utilized to model solid walls. Several improvements were carried out to cure flaws of SPH. The obtained results agree well with the experimental data and prevail against the existing numerical data.
