( 3 ) when f is about fr, the secondary flow reaches its weakest intensity, but has a most complicated structure. for co - rotation and counter - rotation in which the centrifugal force dominates the flow, the secondary flow in a rotating helical pipe has the same direction with that in a stationary one. for counter - rotation in which the coriolis force dominates the flow, the secondary flow has the opposite directions to that in a stationary one
（ 3 ） f在fr左右（離心力和科氏力相當的負旋轉） ，二次流強度最弱，但結構最復雜；對于正旋轉和離心力占優的負旋轉，二次流速度的方向和靜止的情況相同；對于科氏力占優的負旋轉，二次流速度的方向和靜止的情況相反。
