Collaborative Research: Reynolds and Schmidt Number Scalings in Turbulence and Turbulent Mixing: Simulations and Experiments

摘要本文是美国佐治亚理工学院的杨博士与耶鲁大学的Sreenivasan博士（CTS-0121007）关于湍流和湍流混合中的Reynolds和Schmidt数标度的合作研究的一部分。研究将包括模拟和实验。杨博士可以使用NPACI圣地亚哥超级计算机中心的Teraflop IBM SP，他将直接对流动进行数值模拟。有了Teraflop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，使用低温液氦或液氮作为工作流体，这将导致更高的雷诺数流动。将DNS和低温实验在高雷诺数下产生的数据与现有的低雷诺数数据一起用于测试标度定律。两个提案同时发送给审稿人，他们被要求返回一个单独的评估。

AbstractThis proposal is one part of a collaborative research effort between Dr. Yeung of Georgia Tech and Dr. Sreenivasan of Yale University (CTS-0121007) 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.
