摘要

摘要: 系统地阐述了叶素-动量理论在直叶片垂直轴风力机单流管、多流管、双致动盘-多流管气动模型中的应用方法.并根据水平轴风力机叶素动量模型的推导思路,将风轮叶片的切向速度诱导因子引入垂直轴风力机的经典双致动盘-多流管气动模型中加以修正,建立了相应的气动计算模型并用程序仿真实现.与美国Sandia国家实验室的数据进行了对比分析,其气动载荷计算结果与相应实验与模拟结果符合较好,验证了该修正模型的实用与可行性.

Abstract: This paper describes the single streamtube, multiple streamtube and double-multiple streamtube aerodynamic performance prediction models based on blade-element momentum theory for modeling the straightblade vertical axis wind turbine. An improved double-multiple streamtube model considering the tangential induced factor is developed according to the technical route used in horizontal axis wind turbine. Comparisons of the analytical results with the available experimental data from Sandia reports and other relative simulations show a good agreement,which proves the availability and practicability of the modeling method improved in this work.
