Research Initiation Award: Active Excitement of Three- Dimensional Layers

根据研究启动奖，将对超音速两个平行流动之间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。还将进行基于大涡模拟的协调计算工作。高速平行流之间的混合对于先进推进系统的运行和对控制燃烧所必需的混合的有序湍流特征的理解是至关重要的。

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.
