近年来，随着技术的日益进步，风力涡轮机用于能源发电的应用在世界范围内已变得普遍。这些涡轮机在海上的安装遇到了很大的挑战。最重要的挑战之一是由于海浪和水流的相互作用而对这些涡轮机桩周围的冲刷。在这方面已经进行了许多研究；然而，结果还不够充分，而且对三脚架风力涡轮机中的现象仍然知之甚少。在这项工作中，尝试通过将波浪和水流结合起来，并改变涡轮机的下部结构和床层材料的类型，来扩展对这种现象的研究。目前的研究重点是呈现冲刷量的变化趋势。通过改变条件（包括波高的变化、水流速度的变化、桩径的变化、床层颗粒尺寸的变化），可以对冲刷坑的形状和深度进行适当的估计和预测。
In recent years, with daily progress in technology, application of wind turbines for energy generation has become common all around the world. Installation of these turbines at sea encountered a great deal of challenge. One of the most important challenges is scouring around the piles of these turbines due to sea waves and current interaction. Many studies have been conducted in this respect; however, the results are insufficient, and the phenomenon remains poorly understood in tripod wind turbines. In this work, an attempt is made by combining the waves and currents, and changing the substructure of the turbine and the type of the bed materials, to extend the investigation of this phenomenon. The current research is focused on presenting the trend of changes in the amount of scouring. By changing the conditions (including variation in the wave height, variation of the current velocity, variation of the pile diameter, and variation in the size of bed particles), one can arrive at an appropriate estimate and prediction of the shape and the depth of the scour pit.
