Abstract EN
A three-dimensional numerical flume is developed to study cnoidal wave interaction with multiple arranged perforated quasi-ellipse caissons.
The continuity equation and the Navier-Stokes equations are used as the governing equation, and the VOF method is adopted to capture the free surface elevation.
The equations are discretized on staggered cells and then solved using a finite difference method.
The generation and propagation of cnoidal waves in the numerical flume are tested first.
And the ability of the present model to simulate interactions between waves and structures is verified by known experimental results.
Then cnoidal waves with varying incident wave height and period are generated and interact with multiple quasi-ellipse caissons with and without perforation.
It is found that the perforation plays an effective role in reducing wave runup/rundown and wave forces on the caissons.
The wave forces on caissons reduce with the decreasing incident wave period.
The influence of the transverse distance of multiple caissons on wave forces is also investigated.
A closer transverse distance between caissons can produce larger wave forces.
But when relative adjacent distance L/D (L is the transverse distance and D is the width of the quasi-ellipse caisson) is larger than 3, the effect of adjacent distance is limited.
