论文摘要
在本文中，我们提出了一个开源，自动化和多方面的计算统计平台，以获得合成均匀的各向同性湍流和被动标量传输。除了在基于分布式内存CPU的超级计算机上执行统计和少量的湍流传输量的综合记录外，还提供了众所周知的伪谱法的并行实现。用户友好的工作流程和开发软件包的易于运行的设计通过广泛而逐步的示例披露。由此产生的低和高级统计记录生动地验证了建立完善的湍流状态以及无缝的保护法统计平衡。该平台提供的后处理工具将使用户容易从原始的湍流场中构造多个重要的运输量。
In this paper, we present an open-source, automated, and multi-faceted computational-statistical platform to obtain synthetic homogeneous isotropic turbulent flow and passive scalar transport. A parallel implementation of the well-known pseudo-spectral method in addition to the comprehensive record of the statistical and small-scale quantities of the turbulent transport are offered for executing on distributed memory CPU-based supercomputers. The user-friendly workflow and easy-to-run design of the developed package is disclosed through an extensive and step-by-step example. The resulting low- and high-order statistical records vividly verify well-established and fully-developed turbulent state as well as the seamless statistical balance of conservation laws. Post-processing tools provided in this platform would let the user to readily construct multiple important transport quantities from the primitive turbulent fields.
