Therefore blades with a circulationcoefficient of mere than 4 should not be used.
建议不采用环流系数大于4的涡轮叶型。

Hydrodynamics and mass transfer of triplet loop biological fluidized bed reactors were studied in terms of gas holdup, liquid circulation velocity and volumetric mass transfer coefficient.
The loss of efficient head of circulation pump in the primary loop of PWR will increase with the increase of resistance coefficient of JetPump under forced circulation.
