CHARACTERISTICS OF SEAWATER EXCHANGEABILITY ABOUT VERTICAL THIN WALLS WITH SLIT

Abstract

Recently many seawater exchangeable breakwater are constructed for improvement of sea water quality in port and inner harbor. However the mechanism of seawater exchanging is not clear, because of their complex configuration. We study the characteristics of flow through a slit by using hydraulic experiments and a numerical simulation using the volume of fluid method (CADMAS-SURF). It is concluded that the characteristics of flow (direction, velocity, etc.) are related to a pair of vortexes induced by the flow through a slit.
