This paper collects the state of the art and the tremendous progress that has been made in hybrid modeling of aeroacoustic sound. Hybrid modeling is defined such that flow and acoustics are modeled separate and connected by an aeroacoustic model. The contributions will be classified with respect to the aeroacoustic models being developed, covering Lighthill’s analogy, Ffowcs Williams and Hawkings, vortex sound, linearized Euler equations (LEE), and different perturbation equations modeling flow induced sound. Within each topic, specific applications, such as jet noise, aircraft noise, ground mobility, noise, fan noise and human phonation, are covered. We focus on the accomplishments and provide the authors’ contribution to aeroacoustic research. Eventually, a concise summary of the different methods and their capabilities is included.

混合气动声学计算：最新技术和新成就

本文收集了在气动声学混合建模方面的最新技术和取得的巨大进展。混合建模被定义为流动和声学被单独建模并通过气动声学模型连接。这些贡献将根据正在开发的气动声学模型进行分类，包括 Lighthill 的类比、Ffowcs Williams 和 Hawkings、涡流声、线性化欧拉方程 (LEE) 以及模拟流诱导声的不同微扰方程。在每个主题中，都涵盖了特定应用，例如喷气机噪声、飞机噪声、地面机动性、噪声、风扇噪声和人类发声。我们专注于成就并提供作者对气动声学研究的贡献。最后，包括对不同方法及其功能的简明总结。
