摘要 在水煤浆综合输送中试试验台上,将管径为50mm的90°水平弯管配以不同弯径比,对神华煤水煤浆进行了阻力特性试验研究。根据试验结果,对弯管内水煤浆的局部压力损失、摩擦阻力损失及弯管内流动有效长度等方面的一些特性进行总结。结果表明:采用合理的定义及方法,水煤浆弯管内流动的一些特性存在较为明显的规律。 The researches on resistance characteristics are taken out on the coal water slurry(CWS)integrated transport pilot test-bed,the diameter of the 90°side bend is 50 mm and to match different bend ratios.On the base of the experimental results,make some summaries on the characteristics of local pressure loss、friction resistance loose、flowing effective length and so on.It turned out that some characteristics of the CWS flowing in the side bend have obvious patterns if adopt reasonable definition and method.
