旋涡区 meaning in English
vortex cavity
vortex region
Examples
- With computations and analysis , the comprehension on the mixing and combustion process is increased , and some significative results are listed below : a ) there are three recirculation regions and one vortex region in the combustor , and these recirculation regions affect the combustion process deeply , b ) increasing side - arm angle and moving side - air inlet position toward the fuel inlet can improve mixing and combustion characteristics , and increase the combustion efficiency , c ) when the angle between two air - inlets equals to 180
通过计算与分析，增进了对补燃室内掺混燃烧过程的理解，为固体火箭冲压发动机补燃室设计提供了一些有意义的结果： 1补燃室内的流动十分复杂，存在三个回流区和一个旋涡区，回流区对掺混燃烧过程有重要影响； 2增大空气入射角度、向前移动进气道出口位置有利于增强头部回流区强度，增强掺混效果，燃烧效率上升； 3
