1) swirl secondary air
旋流二次风
1.
The experimental results showed that, the flameout at high load arose not from the changes of re-circulation zone and divergent angle, but from the mismatched primary air and swirl secondary air.
试验结果表明:高负荷下的灭火不是由于射流回流区及扩展角的变化引起的,而是由于旋流二次风速过高,导致一、二次风风速不匹配引起的。
2) secondary flow vortices
二次流旋涡
1.
In the present paper, using numerical method mainly and experiment partially, the authors tried to analyze and discuss the generation and the evolution of secondary flow vortices in turbine blade passage.
当今在透平机械行业中的研究人员常常会被二次流旋涡结构的研究所吸引。
3) non-swirl secondary air
直流二次风
1.
When the cones between the swirl secondary air duct and the non-swirl secondary air duct in the burners were removed, the swirl secondary air v.
去掉燃烧器旋流二次风道与直流二次风道之间的扩口后,旋流二次风速度下降,旋流二次风较早地向外扩散,射流的回流区及扩展角略有增加。
4) secondary air jet
二次风射流
1.
The secondary air can’t come to furnace center for low secondary air jet stiffness.
但是随着循环流化床锅炉大型化的发展,出现了许多的问题,二次风射流就是其中最重要的问题之一。
5) helix secondary flow
螺旋型二次流动
1.
The results demonstrate that the heat transfer and pressure loss depend on the helix secondary flow, its mechanisms are due to the working fluid mixing and the development restricting of boundary layers.
结果表明,传热的强化程度与流动阻力的大小取决于螺旋型二次流动的强弱,影响机理是螺旋型二次流动强烈影响流体的混合和边界层的发展。
