Acquiring a 2048 cubed data set of turbulence

大型数值模拟是理解湍流的主要工具之一。随着网格点的增多，流动更加湍急，雷诺数的大值示出了这一点。目前最大的这类模拟是日本新的4096立方体模拟。第二大的是2048年在美国新墨西哥州洛斯阿拉莫斯国家实验室创建的立方体数据集。这个数据集将通过借来的USB磁盘驱动器被带到英国。在这里，我们想用它来识别最容易产生噪音的结构，我们想把它提供给更广泛的英国和欧洲湍流社区，特别是那些试图理解关于湍流的基本数学问题和开发新湍流模型的人。华威将很快从SRIF-2基金获得一个计算和可视化中心，能够处理这类数据集。为研究生和一个帮助每个人访问这些数据的研究协会提供的资金将来自独立的英国应用程序，与英国大学的用户合作。

One of the major tools in understanding turbulence is largenumerical simulations. With more mesh points the flow is moreturbulent, indicated by large values of the Reynolds number.Currently the largest such simulation is the new 4096 cubedsimulation in Japan. One of the next largest is a 2048 cubeddata set created at Los Alamos National Laboratory in New Mexico, USA.This data set is being brought to the UK on loaned USB disk drives.Once it is here we want to use it for identifying those structuremost prone to producing acoustic noise and we want to make itavailable to the wider UK and and European turbulence communities,but especially those trying to understand fundamental mathematicalquestions about turbulence and those developing new turbulence models.Warwick will soon have from SRIF-2 funds a computing and visualization centre capable of handling this class of data set. Funding forpost-graduate students and a research associateto assist everyone in accessing this data will come fromseparate UK applications in collaboration with users fromother UK universities.
