通过风力涡轮机转换的风力正成为主要的可再生能源之一。随着风力涡轮机的尺寸和功率的增长，出现了复杂的工程问题。其中最紧迫的是预测和减少由涡轮机叶片产生的噪声。事实上，尽管一些涡轮机位于海上风电场，但陆上风力涡轮机通常必须安装在居民区附近，并且可能被视为滋扰（Nobbs等人，2012年）。在这一章中，我们提出了一种新的和特别有效的方法来计算翼型周围的湍流产生的噪声。这种方法是基于晶格玻尔兹曼方法（LBM）。LBM是一种非定常计算流体
Wind power converted through wind turbines is becoming one of the main renewable energy sources. As wind turbines grow in size and power, complex engineering problems arise. Among the most pressing is the prediction and reduction of the noise generated by the turbine blades. Indeed, although some turbines are located in offshore wind farms, onshore wind turbines often have to be installed in the vicinity of residential areas and can be regarded as a nuisance (Nobbs et al. 2012). In this chapter, we present a new and particularly efficient approach to compute the noise generated by the turbulent flow around airfoils. This approach is based on the lattice Boltzmann method (LBM). The LBM is an unsteady computational fluid
