Abstract
In this study, a mesh-free method with the explicit solver for the pressure Poisson equation is employed to simulate a dam-break flow. In the method, the incompressibility condition for the water flow is satisfied without the weakly-compressible assumption by using the equation of state in the Smoothed Particle Hydrodynamics (SPH). In the simulation of the dam-break flow, the pressure field is examined to check whether the pressure distribution is smooth or noisy. The pressure distribution at different vertical sections and at different time steps is also investigated. It is found that the pressure distribution is approximately linear at the sections but the pressure at the sections close to the wave front deviates from the linear trend.
