The velocity distribution near the impeller, with high axial velocity and low radial velocity, is the same as ring jet flow.
叶轮区轴向速度较大，径向速度北京化工大学博士学位论文很小，其速度分布与环形射流速度分布类似。
Both the velocity of the sound-excited jet flow at a small circular orifice and the nonlinear impedance of the orifice are measured at high sound intensity.
在高声强下测量了微圆孔处声激发射流的速度和微圆孔的非线性声阻抗。
