Second Order Godunov-Type Scheme for Fluid-Structure Interaction Model of Liquid Piping Systems

Second order explicit finite volume Godunov-Type scheme is formulated for simulation of Fluid-Structure Interaction (FSI) model in this paper. MUSCL-Hancock scheme is applied for calculation of numerical fluxes at cell interfaces. Slope limiter is introduced to obtain high resolution and stable solutions. At the boundaries of the piping systems, the virtual cells are established to restore miss information of parameters. So second order solutions can be obtain in the whole computational domain. The calculating instance shows that the results by the proposed scheme are in close agreements with experimental data.
