摘要

在这项工作中，我们对风速对萨沃纽斯型垂直轴风力涡轮机（VAWT）的空气动力和声学行为的影响进行了数值研究。研究重点是预测风力涡轮机不同流速和转速下的扭矩系数。我们还介绍了风力涡轮机叶片附近的尾流区的触发情况，以了解其对风力涡轮机行为的动态影响。数值模拟研究使用流畅的 CFD 计算代码，使用有限体积法对微分方程进行离散化。通过 SIMPLE 算法，使用两个 K-epsilon 湍流模型来求解流动方程。

Wind Velocity Effect on the Aerodynamic and Acoustic Behavior of a Vertical Axis Wind Turbine

In this work we present a numerical study on the effect of wind velocity on the aerodynamic and acoustic behavior of a Savonius-type vertical axis wind turbine (VAWT). The study focuses on the prediction of the torque coefficient for different flow velocities and rotational velocities of the wind turbine. We also present the triggering of the wake zone near the wind turbine blades to see the dynamic effect on the behavior of the wind turbine. The study of the numerical simulation is carried out using a fluent CFD calculation code using the finite volume method for the discretization of the differential equations. The equations governing the flow are solved by the SIMPLE algorithm using two K-epsilon turbulence models.

期刊介绍： WSEAS Transactions on Fluid Mechanics publishes original research papers relating to the studying of fluids. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of this particular area. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with multiphase flow, boundary layer flow, material properties, wave modelling and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
