Research Initiation Award: Active Excitement of Three- Dimensional Layers

在一项研究启动奖的资助下，将对两股平行流在超音速下的混合层进行实验研究。光学非侵入性诊断和压力测量将用于推断混合的有效性和冲击波的作用。基于大涡模拟的协同计算工作也将进行。高速平行流之间的混合对于先进推进系统的运行和理解控制燃烧所必需的混合的有组织湍流特征是必不可少的。

An experimental investigation is to be conducted, under a Research Initiation Award, of the mixing layer between two parallel streams at supersonic speeds. Optical non-intrusive diagnostics and pressure measurements will be used to infer the effectiveness of mixing and the role of shock waves. A coordinated computational effort, based on large-eddy simulation, will also be carried out. Mixing between parallel streams at very high speeds is essential for the operation of advanced propulsion systems and the understanding of the organized turbulent flow features that control the mixing which is necessary for combustion.
