Analysis of Flow Field in Surf Zone by Accurate Particle Method with SPS Turbulence Model

Simulating turbulence by the standard particle method is difficult due to its unphysical pressure fluctuation. However, the particle method has been improved so as to efficiently suppress such a fluctuation in our previous studies. In this paper, the refined particle method is combined with the sub-particle-scale (SPS) turbulence model. The SPS turbulence model is introduced for the Reynolds stress terms in the filtered Navier-Stokes equation. The standard Smagorinsky model is used in the present study. A spilling breaker is simulated and its turbulent characteristics are analyzed. By comparing with experimental data, a predictive validity of the present simulation is shown.
