Experiment study of heat transfer mechanism and characteristics in high velocitycirculation furnace has been accomplished for batch annealing furnace with high velocity burner.
针对间歇式退火炉使用高速燃烧器，进行了在高速气流循环下的炉内热交换机构与特征的试验研究。

The increase of lobe diffusion angle results in the increase of velocitycirculation at the lobe exit section, but it raises the mixing loss and lowers the pressure recovery coefficient.
扩张角的增加可提高速度环量，但是流动混合损失增加，总压恢复系数减小。

And even if the supply of money were increased, its velocity of circulation might fall, leaving spending unaffected.
