AbstractThis proposal is one part of a collaborative research effort between Dr. Yeung of Georgia Tech (CTS-0120030) and Dr. Sreenivasan of Yale University on the Reynolds and Schmidt number scalings in turbulence and turbulent mixing. The research will include simulations and experiments. Dr. Yeung who has access to the Teraflop IBM SP at the San Diego Supercomputer Center under NPACI will make direct numerical simulations of the flow. With Teraflop capability, simulations will be carried out at much higher resolutions than here-to-fore. Dr. Sreenivasan will carry out experiments in a tunnel using cryogenic liquid helium or nitrogen as the working fluid, which will result in much higher Reynolds number flows. The data generated at high Reynolds numbers both by DNS and cryogenic experiments will be used together with existing data at lower Reynolds numbers to test the scaling laws. Both proposals were sent to the reviewers at the same time, and they were requested to return a single evaluation.

摘要该建议是格鲁吉亚理工学院杨博士（CTS-0120030）和耶鲁大学Sreenivasan博士关于湍流和湍流混合中雷诺数和施密特数定标的合作研究成果的一部分。 研究将包括模拟和实验。 杨博士将直接对流动进行数值模拟，他可以使用NPACI圣地亚哥超级计算机中心的Teraflop IBM SP。 有了Teraflop能力，模拟将以比以往更高的分辨率进行。 Sreenivasan博士将在隧道中使用低温液氦或氮气作为工作流体进行实验，这将导致更高的雷诺数流动。 DNS和低温实验在高雷诺数下产生的数据将与较低雷诺数下的现有数据一起使用，以测试标度律。 这两份提案同时发送给审查人员，并要求他们返回一份评价。
