螺旋盘管流动特性的实验研究

Experimental Investigation of Hydrau lic Character of Spiral Pipes

在一定流量范围内对流体流经平面和立体螺旋盘管进行了流动性能的实验研究 ,得出了盘管折合沿程阻力系数随雷诺数、盘管几何条件及不同盘绕方式等的变化关系曲线及部分经验公式 。

Study the hydraulic cha racter o f plane curved tubes and spiral pipes wh ich have various curved types based on t he experiment in a certain flux range,it provides the correlations of equivalent friction factor versus Renolds number,geometry p roperty,and curved types etc,and compare with straight tube under the same condi tions.
