| 摘 要： | 针对海洋深水试验池造流系统，运用CFD软件对均匀和非均匀垂向流速剖面进行数值模拟，分析研究了试验区域内水流在三个方向上的流速分布情况以及湍流强度的变化，并与目标流速进行了比较。结合模型试验，表明数值模拟的结果是可靠的，深水池能够较为准确地模拟出不同垂向流速剖面的海流，对海洋深水试验池的设计有着重要的参考价值。

| Abstract: | The uniform and ununiform vertical current profiles of the deepwater basin are simulated by using CFD software in this paper. And some analysis have been made, such as the flow uniformities in three directions and turbulence levels. The velocity of the flow is also compared with the target velocity. Combined with model test, it is shown that the results of the simulation are reliable, and the deepwater basin is able to generate different vertical current profiles, which has significant influences on the design of the deepwater basin. |
