Propeller and vortex ring state for floating wind turbines during surge.

这是一个机械工程博士研究项目，更具体地说，在浮动海上风力涡轮机空气动力学。将使用计算流体动力学研究平台沿风向移动时对转子空气动力学性能的影响。所考虑的情况是平台运动高度足以使涡轮机进入螺旋桨状态和涡环状态，这两种情况会导致涡轮机与其自身尾流相互作用，从而显著降低涡轮机的性能。

This is a PhD research project in mechanical engineering, more specifically in floating offshore wind turbine aerodynamics. The impact on the aerodynamic performance of the rotor as the platform moves in the wind direction will be investigated using computational fluid dynamics. The scenarios considered will be those with platform motion high enough to enter the turbine into propeller state and vortex ring state, two events that can lead to a significant reduction in the turbine's performance as a result of the turbine interacting with its own wake.
