万振华,男,中国科学技术大学副教授。2004至2008年在西北工业大学航空学院学习,获得工科学士学位。2008年进入中国科学技术大学近代力学系读博,2013年博士毕业后在近代力学系从事博士后工作。2015至2020年,担任中科大近代力学系特任副研究员,其中,2017-2018年在荷兰Twente大学流体物理组访学,2020年转聘为副教授。主要研究方向为湍流结构与湍流噪声的数值模拟与理论,主持国家自然科学基金项目3项,在Journalof Fluid Mechanics、Physics of Fluids等流体力学刊物上发表SCI论文60余篇。学术**包括《气动研究与实验》编委,深海技术科学太湖实验室客座教授等。报告摘要:
湍流噪声和压力脉动事关飞机、潜艇等重大装备的环保性、隐身性和安全性,它们的生成演化与多尺度湍流结构息息相关,其预测与控制是重要科学难题。本报告首先介绍了湍流噪声预测的高效数值算法,并以射流噪声为例阐释了声源的物理机制并构建了非线性噪声预测模型;其次,采用被动修型、多孔材料、主动激励等控制手段对翼型噪声、弹舱噪声等典型问题进行了有效控制,发展了基于伴随的噪声优化控制方法,并揭示了内在降噪机理;最后,基于大规模直接数值模拟揭示了可压缩壁湍流中的压力脉动的典型特征和规律,考察了压力Hessian张量的物理特性,并发展了适用于可压缩流动的速度梯度张量不变量的动力学模型。![](https://public.fangzhenxiu.com/fixComment/commentContent/imgs/1658995080482_veaw1h.jpg?imageView2/0)
