반잠수식 해양구조물에 작용하는 환경외력에 대한 실험적 연구

Abstract

In this study, the current load acting on a semi-submersible was measured in the wind tunnel. To obtain the uniform flow which resemble current flow, the top of model face down to the floor of wind tunnel. But this installation method cannon ensure the uniform flow because of the floor and generate the boundary layer on the floor. To decrease or eliminate the boundary layer, new experimental equipment was designed and this is height adjustable from the floor. The vertical velocity profiles and current loads were measured for various height and the height was found to give the converged velocity profile and current load.
