专家简介:
肖左利,北京大学工学院力学与工程科学系,教授,湍流与复杂系统国家重点实验室常务副主任。分别于1998年和2001年获得天津大学力学与工程测试系本科和硕士学位;分别于2003年和2008年获得美国南加州大学航空航天系硕士学位和约翰霍普金斯大学机械工程系博士学位。研究方向包括湍流能量级串机理、流体界面不稳定性与湍流混合的物理机理与预测模型、湍流可计算建模与复杂流动模拟,以及可压缩两相湍流离散相与湍流相互作用机理与建模等湍流基础和应用基础研究。压气机是航空发动机的核心部件之一,特别是跨声速压气机内部流动结构十分复杂。因此,准确预测压气机内部的复杂流动结构,提高数值仿真结果的准确度和保真度是压气机数值研究的关键问题。报告首先介绍团队近期发展的雷诺平均纳维-斯托克斯方程(RANS)模拟和大涡模拟(LES)模型。进而介绍跨声速压气机转子叶片标模Rotor 67及Rotor 37定常、非定常工况,Rotor 67半环流场旋转失速的演化过程,以及Stage35 1.5级压气机动静干扰的数值模拟研究工作。![](https://public.fangzhenxiu.com/fixComment/commentContent/imgs/1691686899180_jjtdy3.jpg?imageView2/0)
