Application of incompressible smoothed particle hydrodynamics method for 3D fluid solid interaction problem
Application of incompressible smoothed particle hydrodynamics method for 3D fluid solid interaction problem
A general method for fluid solid interaction problem simulations has been developed in 3D algorithm using incompressible smoothed particle hydrodynamics (SPH) method. The solid is assumed to be rigid so it can be considered as moving boundaries for fluid. Using repulsive force has been proved to be an efficient boundary treatment for incompressible SPH method before with 2D examples. The advantage of this boundary treatment will be more obvious in 3D simulations of fluid-structure interaction problems since that it requires the fewest particle numbers on the boundaries compared with other boundary treatments. The algorithm can be applied to fluid solid interaction problems with deformable solid by using elastic or plastic solid theories. In this paper, 3D dam-breaking is used as an example to demonstrate the performance of this method and aircraft ditching is simulated.

Abstract
A general method for fluid solid interaction problem simulations has been developed in 3D algorithm using incompressible smoothed particle hydrodynamics (SPH) method. The solid is assumed to be rigid so it can be considered as moving boundaries for fluid. Using repulsive force has been proved to be an efficient boundary treatment for incompressible SPH method before with 2D examples. The advantage of this boundary treatment will be more obvious in 3D simulations of fluid-structure interaction problems since that it requires the fewest particle numbers on the boundaries compared with other boundary treatments. The algorithm can be applied to fluid solid interaction problems with deformable solid by using elastic or plastic solid theories. In this paper, 3D dam-breaking is used as an example to demonstrate the performance of this method and aircraft ditching is simulated.
