A CASE STUDY ON SETTELEMENT OF SESSILE ORGANISMS UNDER OSCILLATING FLOW IN A WAVE-POWER STATION

Abstract

A series of experiments for understanding settelement of sessile organisms inside of caission at the wave-power station were conducted. The mean velocity and turbulent components in the caission were measured by Particle Image Velocimetry (PIV). The effects of oscillating velocity and pressure of the flow on the settlement of barnacle cyprids were exmained by the two different series of experiments. The experimental data shows both velocity and pressure oscillations inhibit significantly larval settlement of barnacle cyprids on the floor.
