Abstract

Smoothed Particle Hydrodynamics (SPH) is becoming a useful tool for examining hydrodynamic flows that are difficult to model with other existing numerical methods, such as time-dependent flows with convoluted free surfaces. This paper will describe the development of the method using interpolation, and then present some applications to free surface flows, primarily water waves. The ability of the method to easily handle large free surface deformations, including wave breaking, will be illustrated. Finally the ability of the SPH method to solve for other non-hydrodynamic variables is shown-here we solve for the suspended sediment concentration under waves.
