High Mach Number, Chemically-Reacting Turbulent Mixing Layer

摘要Ladeinde 9626413 PI建议使用直接数值模拟（DNS）研究超音速、湍流、反应流。 建议的工作的目的是扩展他们以前的研究可压缩湍流（马0.7），标量平流，反应流和并行处理化学反应可压缩湍流的所有影响相结合。 拟议的研究将涉及应用于马赫数高达3.0的时间混合层的三维湍流计算，包括放热、非预混、可逆、一步、四组分反应。 本研究将利用大规模平行架构上的ENO格式的有限差分程序。 这项调查希望产生的信息与物种传输，化学生产和湍流结构的密度波动的相互作用。

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.
