Design of a Hydraulic-Control Wave-Maker (HCW) for the Study of Oceanographic Flows


This study aims to verify new approach to generate and absorb waves by using a system termed the Hydraulic-Control Wave-maker (HCW). The experimental device would eventually permit the study of multi-scale and vertically-variable oceanographic flows. The HCW has upstream and downstream flume boundaries composed of an adjustable set of vertical chambers. Each chamber is connected to an individual pump control system, such that the vertical distribution of flow is entirely controllable. In this study, a numerical tank with a HCW is created with OpenFOAM�, and results are compared with various analytical solutions. To generate sine wave and solitary wave, horizontal particle velocity from linear wave theory and solitary wave theory are used. The optimized HCW is investigated through sensitivity analyses with respect to baffle length, height, number and position. The method of wave absorption is applied by the similar technique with wave generation to downstream boundary. For the application to deal with wave absorption in practical, numerical analyses that the velocity profile from any station to outlet boundary can be shifted by using wave celerity are performed.
