Abstract: The mesh-free Smoothed Particle Hydrodynamics (SPH) method is a new generation high-performance numerical modeling technique. The key feature of the method is totally mesh-free, without using any grid or mesh in the computational domain. Therefore, the governing hydrodynamic equations are discretized by the moving particles, and the free surface, material interface, wet-dry boundary etc. can be automatically solved without resorting to complicated mesh treatment.
The proposed seminar recalls the development of SPH approach, presents its core methodology, demonstrates its diverse applications in coastal and hydraulic field, and visualizes its great potentials to solve practical engineering problems in the foreseeable future. The presentation covers some interesting project examples, including dam break, wave breaking and overtopping, wave-structure interaction, water entry and exit, turbulent flow, porous flow and multi-phase flow, etc.
