Modeling capability of performing a fully coupled high-resolution numerical modeling of fluid-structure interaction, with particular focus on improving our understanding of the nonlinear response and impact of wave energy converters (WECs). The modeling framework couples an open-source 3D Smoothed Particle Hydrodynamics (SPH) model GPUSPH (www.gpusph.org) with an open-source multi-physics simulation engine Project Chrono (www.projectchrono.org). The coupled model simultaneously resolves the dynamics of a moving body (e.g., WECs) and the surrounding turbulent flow. The Lagrangian GPUSPH model results are available at SPH nodes, or particles, that are distributed irregularly in space as they move with the fluid around a moving object. The dynamics of the moving body are then computed by the Project Chrono model using the hydrodynamic force provided by the GPUSPH model.
The model is implemented on GPUs and is relatively computationally efficient. The model has been successfully used for studying various scientific and engineering problems involving nonlinear and breaking surface gravity waves. The coupled model is capable of simulating multi-body systems. One of the current model developments focuses on extending the model capability to resolve flexible objects.
