Abstract

The present paper presents the aeroacoustic calculation methodology for the H-Darrieus wind turbine. The CFD analysis, for different wind turbine blades? angles of attack, coupled with the noise analysis, based on Lighthill and Prudmann models is performed. This type of turbine is of particular interest since it is insensitive to wind direction and can be used in urban areas. In this study commercial software, ANSYS is used for CFD and aeroacoustic analysis. The required turbulent flow field is calculated based on the standard k-? model, and reequired model constants are obtained experimentally in a low-Mach number wind tunnel. The noise levels generated by operating turbine are calculated based on Lighthill and Proudman's aeroacoustic theories. It was found that the methodology presented can be efficiently used in noise analysis of vertical axes wind turbines and due to recent strict noise regulations has to be deployed at the early design stages.

三叶片h-Darrieus风力机气动噪声分析方法

本文介绍了H-Darrieus型风力机的气动声学计算方法。不同风力涡轮机叶片的CFD分析?在Lighthill模型和Prudmann模型的基础上，进行了攻角和噪声分析。这种类型的涡轮机特别有趣，因为它对风向不敏感，可以在城市地区使用。本研究采用商用软件ANSYS进行CFD和气动声学分析。所需的湍流流场是根据标准k-?模型，并在低马赫数风洞中实验得到了所需的模型常数。基于Lighthill和Proudman的气动声学理论，计算了涡轮运行时产生的噪声级。结果表明，所提出的方法可以有效地用于垂直轴风力涡轮机的噪声分析，并且由于最近严格的噪声法规必须在早期设计阶段部署。

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
