Numerical Simulation of Sphere Impacting Water by SPH with Hydrodynamics

Abstract:

The impact on water of aeronautical structures is likely to turn into a tragic event. In view of this, it is essential to develop new solutions to design worthy structure that can assure best behavior. The Smoothed Particles Hydrodynamics (SPH) is a mesh-free interpolation method which is a recent numerical analysis technique. One example of water impact based on SPH is presented here, which aims at an accurate numerical simulation of Fluid-Structure Interaction(FSI) in free surface flow context. The example describes a rigid sphere impacting onto water, presenting the global impact behavior as well as comparing the impact coefficient with analytical and experimental results. The SPH method is proved to be a reliable and efficient numerical tool.
