| 摘 要： | 本文在分析前人工作的基础上,考虑了由水煤浆屈服应力所引起的管内速度分布的变化,理论分析了水煤浆在管内的流动情况,提出了水煤浆管阻特性的理论计算方法,并对其进行了大量的试验验证。实验结果与理论分析十分吻合,说明本计算方法可以用于实际工程的设计。

| Abstract: | Based on the analysis of pervious work about Coal Water Slurry (CWS), this paper considered the varying of flow velocity distribution inside pipe caused by the yield stress of CWS, analysed the pipe flow of CWS theoritically and proposed a theoritical calculating method of pipe flow drag of CWS. Also, a lot of experiments have been carried out to identify the method. The experimental results correspond to the theoritical analysis very well. This calculating method can be applied to the disign of practical engineering of CWS. |
