Abstract

In this preliminary work, we would like to demonstrate some flow applications of our in-house 3D Fluid Structure Interaction (FSI) simulation software that we have developed at University of Nottingham Malaysia (UNM). This mesh-less FSI simulation software is developed based on the Smoothed Particle Hydrodynamics (SPH) and Volume Compensated Particle Method (VCPM) for fluid and solid modelling respectively. A force coupling algorithm has been developed to couple the fluid and solid body solvers. Recently, the algorithm has been implemented in an open-source C++ code (i.e. DualSPHysics) so that complex large-scale 3D problem can be simulated within a reasonable time frame by making use of the Graphical Processing Unit (GPU) technology. A few simulation cases are highlighted in order to show some potential applications of this FSI method.
