Collaborative Research - Reynolds and Schmidt Number Scalings in Turbulance and Turbulent Mixing: Simulation and Experiments

这项建议是佐治亚理工学院的杨博士(CTS-0120030)和耶鲁大学的斯里尼瓦桑博士就湍流和湍流混合中的雷诺和施密特数标度进行的合作研究的一部分。这项研究将包括模拟和实验。杨博士在NPACI下属的圣地亚哥超级计算机中心使用了万亿次浮点IBM SP，他将对这一流动进行直接的数值模拟。有了万亿次浮点的能力，模拟将以比以前高得多的分辨率进行。斯里尼瓦桑博士将在隧道中进行实验，使用低温液氦或氮气作为工作流体，这将导致更高的雷诺数流动。在高雷诺数和低温实验中产生的数据将与现有的低雷诺数数据一起用来检验标度律。两份提案同时送交审查员，他们被要求退回一份评估报告。

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.
