Thee diffuser length should be long enough to ensure the main flow deceleration.
扩压段应具有一定的长度以保证主气流减速到一定程度。 。
The study shows that complex flow separation in the diffuser can be effectively brought under control by external acoustic excitation.
实验结果表明用外部声激励的方法可以控制小展弦比扩压器内的复杂分离流动；
This model also can be used for the internal flow calculation of any two-dimensional diffuser and for improving its design.
本文的计算方法还可以应用于任意二维扩散器的内部流动计算，用来指导改进扩散器的设计。
