Abstract: A modified Smoothed Particle Hydrodynamics(SPH) in Lagrangian-averaged Navier-Stokes-alpha(LANS-α) model was developed to simulate water entry flow.Water entry of a half buoyant cylinder and a neutrally buoyant cylinder were simulated.SPH results are in good agreement with reported experiments and numerical results of others.It shows that the modified SPH method is practicable in simulation of water entry flow.

Key words: SPH method, water-entry flow, free surface flow
