Compressible Shear-Layer Mixing Experiments

这笔赠款将支持实验研究的影响， 在同向流动的流之间混合的压缩性。 混合层中的对流马赫数将从 低至3。 几何特征及其 演化和相互作用将被研究，与光学 包括平面瑞利散射和平面 激光诱导荧光 已知两种流之间的混合在高温度下会劣化。 相对流速，但原因尚不清楚。 对高速混合层的认识和控制是 在燃烧和推进系统中至关重要。

This grant will support experimental research on the effect of compressibility on mixing between co-flowing streams. Convective Mach numbers in the mixing layers will vary from low to as high as 3. The geometrical features and their evolution and interactions will be studied, with optical diagnostics including planar Rayleigh scattering and planar laser-induced flurescence. Mixing between two streams is known to be degraded at high relative flow velocites, but the reason is not yet understood. Understanding and control of high speed mixing layers is of crucial importance in combustion and propulsion systems.//
