杨小权,上海大学副教授、博士生导师,力学系系副主任。曾获得了C919飞机首飞突出贡献奖和上海市力学学会优秀青年学者奖。担任中国空气动力学会计算空气动力学/低跨超声速专委会委员,中国力学学会计算流体专业组员、吉林大学学报工学版青年编委。研究领域为计算流体力学、航空飞行器空气动力学和气动声学。提出并发展了鲁棒高效的非结构网格隐式有限体积湍流与噪声数值模拟方法和高阶间断伽辽金湍流与噪声数值模拟方法,开发的求解器集成到了国家数值风洞和航空发动机数值仿真软件。提出了飞机增升装置缝翼凹腔波纹噪声控制技术和起落架主支柱波纹噪声控制技术,取得了较好的减阻降噪效果。报告摘要:
航空飞行器复杂构型湍流与噪声数值模拟方法和求解技术面临最大的挑战是数值鲁棒性差、收敛困难的难题。讲座分为湍流数值方法和噪声数值模拟两个部分:第一部分重点讲解鲁棒高效的非结构网格隐式FV和DG方法的构造;第二部分重点讲解上海大学现代飞行器空气动力学研究团队在大型客机增升装置和起落架湍流噪声机理与控制技术的研究进展。(本文为杨小权老师在2022年湍流与噪声及CFD方法暑期高级讲习班的报告)![图片](https://public.fangzhenxiu.com/fixComment/commentContent/imgs/1658978654242_o3vy3b.jpg?imageView2/0)
