High Mach Number, Chemically-Reacting Turbulent Mixing Layer

PIs提出了一种使用直接数值模拟（DNS）来研究超音速、湍流、反应流的方法。这项工作的目标是将他们之前对可压缩湍流（Ma 0.7）、标量平流、反应流和平行处理的研究扩展到化学反应可压缩湍流，其中所有的影响都结合在一起。拟议的研究将涉及三维湍流计算，应用于马赫数高达3.0的时间混合层，包括放热、非预混、可逆、一步、四种反应。本研究将采用基于ENO方案的有限差分程序进行大规模并行架构。这项研究希望能提供密度波动与物种迁移、化学产物和湍流结构之间相互作用的信息。

Abstract Ladeinde 9626413 The PIs propose a study of supersonic, turbulent, reactive flows using direct numerical simulation (DNS). The objective of the proposed work is to extend their previous studies on compressible turbulence (Ma 0.7), scalar advection, reacting flows and parallel processing to chemically reacting compressible turbulence where all the effects are combined. The proposed study will involve three dimensional turbulence calculations applied to a temporal mixing layer at Mach numbers up to 3.0 and including an exothermic, non -premixed, reversible, one-step, four species reaction. A finite difference procedure based on ENO scheme on massively parallel architecture will be utilized in this study. This investigation hopes to yield information about the interactions of density fluctuations with species transport, chemical production, and turbulence structure.
