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.

摘要CTS-0084362 E。俄亥俄州萨米米州立大学研究基金会高速（可压缩气体）喷流在运输机和军用飞机上具有明显的重要性。 它们也被广泛用作喷射器、喷嘴流等。与它们的低速对应物不同，这些流还没有得到研究界的广泛研究。 一个限制性的问题是适当的诊断技术的可用性。Co-PI的带来了相当多的经验和洞察力，在这种射流的基本湍流特性的计划研究。 为期一年的资助是为了使他们能够解决已经提出的关于他们的实验方法和数据的关系，他们的理论/数值同事的需求的关注。
