项目摘要

With the increasing global appetite for wind power and worldwide government incentive schemes to promote wind industry growth a plethora of wind turbine concepts are being manufactured. Generally the concepts are split into two classes: horizontal axis wind turbines (HAWT) with rotation about a shaft pointing into wind and vertical axis wind turbines (VAWT) with rotation about a vertical shaft. The vast majority of research and development work undertaken in this industry has focused on large two and three bladed HAWTs. As a result there are analytical tools available for most aspects of rotary aeromechanic performance and loads analysis of HAWTs but there are no rotary aeromechanics analytical methods available for VAWTs or for mirco and small HWATs with four blades or more. Currently design work of VAWT and small HAWT must use analytical approximations, generally neglecting unsteady aerodynamic effect. The need to model unsteady aerodynamics, in order to correctly predict loads and performance is well establish in the HAWT research community. This capability is also vital for the accurate prediction of loads and performance in VAWT systems.This project seeks to develop and validate a rotary aeromechanics analysis code to simulate the performance, loads and vibration of VAWTs and micro and small HAWTs to support design, certification and siting analysis requirements.

随着全球对风力发电的需求不断增长，以及全球政府为促进风电行业发展而制定的激励计划，大量的风力涡轮机概念正在被制造出来。一般来说，这些概念分为两类：围绕指向风的轴旋转的水平轴风力涡轮机（HAWT）和围绕垂直轴旋转的垂直轴风力涡轮机（VAWT）。该行业进行的绝大多数研发工作都集中在大型两叶和三叶轴风力机上。因此，对于 HAWT 的旋转式空气力学性能和载荷分析的大多数方面都有可用的分析工具，但没有适用于 VAWT 或具有四个或更多叶片的微型和小型 HWAT 的旋转式空气力学分析方法。目前垂直轴风力机和小型水平轴风力机的设计工作必须使用解析近似，一般忽略非定常气动效应。 HAWT 研究界已经明确需要对非定常空气动力学进行建模，以便正确预测载荷和性能。此功能对于准确预测 VAWT 系统的负载和性能也至关重要。该项目旨在开发和验证旋转空气力学分析代码，以模拟 VAWT 和微型和小型 HAWT 的性能、负载和振动，以支持设计、认证和选址分析要求。
