深海工程试验水池造流装备研究

Research on The Generation of Current in A Test Basin for Deepwater Engineering

海洋工程结构物诸如浮式石油平台、海洋可再生能源装置等进行设计时,海流是一个重要的环境影响参数,尤其在深海恶劣的环境中。在波浪水池开展模型试验时往往需要考虑海流的作用,因此如何实现海流的模拟显得尤为重要;然而精确的模拟海流是十分困难的,本文总结了当今世界上著名的海洋工程实验室的造流装置特点并分析了其造流的方法,如拖曳法,围绕假底上下循环造流法,局部造流法,池外循环造流法,主要目的是更好的理解造流方法并为未来深水池设计提供有益的借鉴。

Ocean current is an important environmental parameter that influences the design of offshore structures,such as floating oil platforms and marine renewable energies devices,particularly in harsh environment. Simulated environment in a model test often includes current effect. Therefore, simultaneous simulation of current in the wave basin is desirable. Accurate modeling of current in a laboratory environment is,however,a difficult task. This paper summarizes the current generator facilities of nowadays some famous test basins and also surveys the methodology of the generation of ocean current in these test basins,such as towing of the model replacing current,generation of current by closed loop surrounding a faise floor,local current generation,and generation of current by recirculating outside the basin. The aim of this paper is to provide a better understanding of current generation methodology,and to provide a useful reference for future wave basin design.
