Abstract

A 3-D model for irregular wave propagation over partly vegetated waters is established using the Navier-Stokes equations with the RNG k-ε turbulence model and VOF method to capture the free surface. The model is based on FLUENT and utilizes User-Defined Functions (UDF). The applicability of the proposed model is assessed thoroughly by test cases of open channel flow through vegetation, flow in a partly vegetated open channel, uni-directional irregular wave propagation over waters with vegetation and multi-directional irregular wave refraction and diffraction over an elliptic shoal. The computed results agree well with the experimental data. Finally, the case of multi-directional irregular wave propagation over partly vegetated waters is simulated to show the effect of a vegetated zone on the wave characteristics.
