Part three: numerical simulation on the supersonic chemically reacting flow field in the combustors.

主要工作包括三部分：第一，雾化后的燃料液滴和气态燃料在燃烧室的超声速气流中混合问题的数值模拟。

This is impractical for engineering problem. It is necessary to break the shear layer in order to enchance mixing. It is very useful for combustor design with cavity or dual-cavity. In such combustor the fuel jet can break the

要使超声速混合增强，必须打破稳定的剪切层，燃烧室采用凹槽或双凹槽设计是一种行之有效的方法，它产生的燃料射流就能打破剪切层，从而使混合和燃烧效率进一步提高。

It turns out that the flow and noise characteristics are quite complex and different from those of incompressible jets due to existence of quasi-periodic shock cell structures.

超声速射流是一般工业和军事工业中得到广泛应用的重要流动现象，对其流动特性和声学特性的研究，在实际应用和学术研究上有重要的理论价值和实际意义。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
