Numerical simulation of fluid structure interaction in water entry problems by smoothed particle hydrodynamics method
Water entry problems are investigated and the fluid structure interaction problems within the entry process are studied by a gridless method named smoothed particle hydrodynamics (SPH) method.Firstly, the SPH model is described briefly which includes numerical approximation, the discretized governing equations, solid body motion, boundary treatment and time step algorithm.Then the SPH method is testified by an inclined wedge water entry case to validate the accuracy of the current method.Afterwards, a 2-D wedge water entry case is performed to figure out the maximum slamming force exerted on the wedge in the interaction process, and results are verified by both experimental data and theoretical solutions.Lastly, a 3-D wedge water entry case and a 3-D skipping stone case are simulated respectively.Also, parts of the results are compared with experiment.Good agreements are made in the paper which proves that SPH method is good to simulate the fluid structure interaction phenomena in water entry problems.
