Smoothed Particle Hydrodynamics: Methodology and Applications
Dr.Robert A. Dalrymple
Civil Engineering,
Johns Hopkins University.
Smoothed particle hydrodynamics, a meshless Lagrangian computational method, was originally developed in astrophysics, but has recently been applied to a number of fields, including hydrodynamics. For free surface flows, the method is simpler to apply than traditional computational techniques, as the free surface equires no special treatment---splashing and wave breaking present no difficulties.
The talk will discuss the development of the method for
fluid flow, and then discuss a number of preliminary applications, including
water waves solitary wave breaking, overtopping, landslide-induced tsunamis),
wave-structure interaction, and flow past submerged objects (hydrofoil).
