自古以来，人类就尝试通过多种方式利用风能，垂直轴风力发电机（VAWT）是实现这一目标的主要设备之一。在当今时代，随着众多大学和研究机构开展了广泛的研究活动并开发了基于多种空气动力学计算模型的众多设计，人们对 VAWT 的兴趣重新兴起。这些模型对于推导最佳设计参数以及在制造 VAWT 之前预测性能至关重要。在这篇综述中，作者试图编译用于直叶片 Darrieus 型 VAWT 性能预测和设计的主要空气动力学模型。研究发现，目前应用最广泛的模型是双多重流管模型、Vortex模型和Cascade模型。这三种模型各有其优点和缺点，本文对此进行了讨论。
Since ancient past humans have attempted to harness the wind energy through diversified means and vertical axis wind turbines (VAWTs) were one of the major equipment to achieve that. In this modern time, there is resurgence of interests regarding VAWTs as numerous universities and research institutions have carried out extensive research activities and developed numerous designs based on several aerodynamic computational models. These models are crucial for deducing optimum design parameters and also for predicting the performance before fabricating the VAWT. In this review, the authors have attempted to compile the main aerodynamic models that have been used for performance prediction and design of straight-bladed Darrieus-type VAWT. It has been found out that at present the most widely used models are the double-multiple streamtube model, Vortex model and the Cascade model. Each of these three models has its strengths and weaknesses which are discussed in this paper.
