海流涡轮机阵列的发展多年来一直是一个活跃的研究课题。然而，为了充分理解这种阵列的行为，仍然需要进行许多研究。其中一项研究是环境湍流对海流涡轮机性能的影响。事实上，最近的研究表明，环境湍流强度大大改变了水平轴海流涡轮机的行为。因此，数值模拟必须代表环境湍流或至少其对涡轮机性能和尾流的影响。本文介绍了LOMC与法国海洋所合作进行的最新数值研究，以考虑环境湍流的影响。
The development of marine current turbines arrays has been an active research topic for some years. However, many studies are still necessary in order to fully understand the behaviour of such arrays. One of these studies is the impact of the ambient turbulence on the behaviour of marine current turbines. Indeed recent studies have shown that ambient turbulence intensity highly modifies the behaviour of horizontal axis marine current turbines. Consequently numerical simulations have to represent the ambient turbulence or at least its effects on the performance and wake of the turbines. This paper presents the latest numerical developments carried out at LOMC in collaboration with IFREMER in order to take into account the effects of ambient turbulence.
