A five hole probe is used for measuring the tangentialAngle of flow, axial velocity, static pressure of flow and swirl number in the flow sections of the conveying system.
应用五孔感头测定沿程截面内气流的切向角、轴向速度、气流静压和旋流数的分布。

The angle of alpha will then be tangential to this point.
α角将,与该点相切。

The combination of radial and tangential fretting was realized by changing the inclined Angle of specimens on a newly developed radial fretting tester.
