摘要
对用于产生螺旋管流的圆管螺旋流起旋器的结构参数进行了分析 ,并对其阻力特性进行了理论分析和试验研究。研究表明 ,圆管螺旋器的阻力公式形式与达西公式相同 ,但其阻力系数不仅包括了达西阻力系数 。
The structure parameters and resistance characteristics of spiral pipe flow generator which generates spiral flow in circle pipe were analyzed and investigated. It was found that the resistance formula type of spiral pipe flow is the same as Darcy ,s formula, but its resistance coefficient includes not only Darcy ,s resistance coefficient but also the structure parameters of spiral pipe flow generator.
