| 摘 要： | 螺旋流管道输固在一定程度上可以解决传统管道输送方式存在的高浓度与低能耗的矛盾.起旋器是螺旋流产生的重要装置,采用模型试验与理论分析相结合的研究方法,对其内部的旋流特性进行了研究.结果表明:导流片对流速和涡量变化都有重要影响.导流片附近速度梯度较大;在同一断面,雷诺数相同时,各方向的流速等值线图十分相似,且各方向的流速等...

| Abstract: | Solid materials transport by spiral flow in a pipe can effectively solve in some sense the existing contradiction of high concentration and low energy consumption in traditional pipe transport.In this work,the spiral flow in a local generator,a key device to maintain the spiral system,was studied by a combination of theoretical analysis and model experiments.The research findings show that the generator guide vanes have significant influence on flow rate and vorticity.Velocity gradients vary greatly near th... |
