velocity of discharge

Because of the distinct reducing of the swirl velocity and the instability of the forced vortex itself, the vortex at the volute discharge section breaks down easily, inducing the reverse flow at the center of volute discharge section.

在蜗壳出口直管段由于涡流速度明显减小和旋涡自身的不稳定，在小流量下容易发生破裂，导致蜗壳出口的截面中心区域通流速度均出现逆流，此逆流为压缩机失速特征的表现。
