Exploring Turbulence Structures in High Speed Jets Using Advanced Optical Diagnostics

摘要CTS-0084362E。俄亥俄州立大学萨米米研究基金会高速(可压缩气体)喷流在运输和军用飞机中具有明显的重要性。它们还被广泛用作喷射器、喷嘴气流等。与低速气流不同，这些气流还没有得到研究界的广泛研究。一个限制性的问题是合适的诊断技术的可用性。Co-Pi为计划中的这种射流的基本湍流性质的研究带来了相当多的经验和见解。为期一年的资助是为了使他们能够解决对他们的实验方法以及数据与他们的理论/数字同事的需要的关系提出的关切。

AbstractCTS-0084362E. Samimy, Ohio State University Research FoundationHigh-speed (compressible gas) jet flows are of obvious importance in transport and military aircraft. They are also widely utilized as ejectors, blast nozzle flows, etc. Unlike their low speed counterparts, these flows have not received extensive study by the research community. One limiting issue is the availability of appropriate diagnostic techniques.The Co-PI's bring considerable experience and insight to the planned studies of basic turbulence properties in such jet flows. The one-year funding is to permit them to address the concerns that have been raised regarding their experimental methods and the relationship of the data to the needs of their theoretical/numerical colleagues.
