高军辉,北京航空航天大学能源与动力工程学院副教授,科研方向包括喷流噪声、机体噪声和高精度数值方法。紧密围绕国家在大型民用客机和大涵道比涡扇发动机噪声方面的重大需求,在气动声学领域的高精度数值模拟方法、复杂流动发声机理等方面持续开展多年研究,主要研究成果发表在 AIAA Journal, Journal ofFluid Mechanics , Journal of Computational Physics , Journal of the AcousticalSociety of America 以及 Physics of Fluids 等本领域的著名期刊上,发展的高精度流动与噪声数值模拟软件集成到航发集团“航空发动机数值仿真平台”中。报告摘要:
讲座内容分为两部分,首先介绍高精度谱差分方法,以及针对声学数值模拟的格式优化研究;其次介绍高精度谱差分方法在气动噪声数值模拟上的应用,包括喷流噪声、风扇噪声、螺旋桨噪声等。
