SPH MODEL TO SIMULATE MOVEMENT OF GRASS MEADOW OF POSIDONIA UNDER WAVES

Abstract

The objective of this paper is to try a new approach to simulate the interactions between waves and algae. The chosen method is to simulate waves and plants through SPH (Smoothed Particle Hydrodynamics, SPH). In this model, the algae are defined as a solid that respects Hook's law, which is in direct interaction with the fluid part. Given the properties of this method especially in terms of computation time, the dimensions of the simulations are limited. A successful representation of the movement of algae under waves or/and current by SPH will permit the determination of coefficient of friction corresponding to a type of algae, that can be used in a different larger scale code.
