This paper presents an improved SPH model for simulating the complex process of free surface flows with moving rigid objects. The SPH model contains corrections on the SPH kernel and kernel gradients, enhancement of solid boundary and solid–fluid interface treatment, and implementation of Reynolds-averaged Navier–Stokes turbulence model. The effectiveness of the SPH model has been demonstrated by three numerical examples including the water exit of a cylinder, the sinking of a submerged cylinder and the complicated motion of an elliptical cylinder near free surface.
