DeepWind 项目旨在研究新型浮动垂直轴风力涡轮机 (VAWT) 概念的可行性，其目的是开发深水近海站点的风力资源。这里展示了 DeepWind 缩小规模演示机上针对不同风速和转子角速度的广泛实验活动的结果，还包括由于倾斜转子布置而导致的偏流运行。为了实现这一目标，在测量气动功率和推力（流向和横向）后，在高精度测试台上安装了 troposkien 三叶片转子，其轴线相对于设计（即直立）操作条件倾斜最多 15°。实验在米兰理工大学（意大利）的大型高速风洞中进行，使用“自由射流”（开放通道）配置。还通过仪表横动系统对转子尾流中的速度场进行了充分表征，以研究测试段下游的流量分布。在描述实验装置和测量数据时特别注意，以便当前结果可以用作仿真模型验证的基准。
The DeepWind Project aims at investigating the feasibility of a new floating vertical-axis wind turbine (VAWT) concept, whose purpose is to exploit wind resources at deep-water offshore sites.The results of an extensive experimental campaign on the DeepWind reduced scale demonstrator are here presented for different wind speeds and rotor angular velocities, including also skewed flow operation due to a tilted rotor arrangement. To accomplish this, after being instrumented to measure aerodynamic power and thrust (both in streamwise and transversal directions), a troposkien three-bladed rotor was installed on a high precision test bench, whose axis was suitable to be inclined up to 15° with respect to the design (i.e. upright) operating condition.The experiments were performed at the large scale, high speed wind tunnel of the Politecnico di Milano (Italy), using a “free jet” (open channel) configuration. The velocity field in the wake of the rotor was also fully characterized by means of an instrumented traversing system, to investigate the flow distribution downstream of the test section.Special care is taken in the description of the experimental set-up and of the measured data, so that the present results can be used as a benchmark for the validation of simulation models.
