DESIGN OPTIMIZATION FOR A PASSIVE MESH SCREEN WAVE ABSORBER FOR THE CCOB

A new passive wave absorber, consisting of multiple mesh screens, for the Cantabria Coastal and Ocean Basin (CCOB) was optimized regarding its overall length and performance. Physical model wave flume tests were conducted to calibrate and verify a 2D-RANS model utilizing different combinations of vertical and horizontal mesh screens. The final design of the main wave absorber at the back wall of the new CCOB was obtained by simulating different mesh screen configurations at full scale using the IH-2VOF model. Very good wave absorption over the entire working range of the wave basin could be achieved with a relatively short passive mesh screen wave absorber.
