| 摘 要： | 测定了雷诺数Ｒｅ从６８变化到１６５１时混合器压力降与雷诺数，摩擦系数与雷诺数的关系曲线和相应的曲线拟合方程。Ｒｅ＜５５０时，摩擦系数ｆ＝１３９．６６Ｒｅ－０．７４２，当Ｒｅ＞５５０时，流动基本处于湍流状态，ｆ＝５．２Ｒｅ－０．２０３。当雷诺数增大时，混合器内元件数量的改变对摩擦系数影响不大。

| Abstract: | For a new kind of pulsed static mixer,the curves and simulation correlation of f Re and ΔP Re were presented respectively,which cover the Reynolds Number from 68 to 1651.At the value of Re below 550,the laminar flow is maintained,then f =139.66 Re -0.742 .When Re is greater than 550,the turbulent flow is found and f=5.2Re -0.203 .The experiments also show that the quantity of the elements in static mixer has no influences on the friction factor when the Reynolds number is greater. |
