Investigations of boundary treatments in incompressible smoothed particle hydrodynamics for fluid-structural interactions
Investigations of boundary treatments in incompressible smoothed particle hydrodynamics for fluid-structural interactions
Two boundary treatment methods were developed for incompressible flow simulations and fluid-structural interaction problems using Smoothed Particle Hydrodynamics (SPH): 1) To apply repulsive force on the boundary particles while keeping the same particle spacing for inner fluid particles and wall boundary particles; 2) To use denser wall particles without any additional force. The dam-breaking problem and another testing example are used to demonstrate the performance of this method. Results obtained from the present approach show reasonable agreement with experimental data. The fluid pressure values obtained with SPH method is investigated. Based on the result of the study, it can be concluded that the present approach is reliable to simulate incompressible fluid and the pressure value obtained can be used to solve fluid-structural interaction problems.

Abstract
Two boundary treatment methods were developed for incompressible flow simulations and fluid-structural interaction problems using Smoothed Particle Hydrodynamics (SPH): 1) To apply repulsive force on the boundary particles while keeping the same particle spacing for inner fluid particles and wall boundary particles; 2) To use denser wall particles without any additional force. The dam-breaking problem and another testing example are used to demonstrate the performance of this method. Results obtained from the present approach show reasonable agreement with experimental data. The fluid pressure values obtained with SPH method is investigated. Based on the result of the study, it can be concluded that the present approach is reliable to simulate incompressible fluid and the pressure value obtained can be used to solve fluid-structural interaction problems.
