摘要
阐述了矿浆的物理性质、紊流特性和阻力特性,介绍了几种常见的用于管道输送浆体水力计算经验公式,并分析了其适用范围和优缺点,为选煤行业合理选用经验公式提供了有益参考。
The paper described the physical characteristics, turbulent flow features and resistance proper- ty of the slurry, introduced several commonly used pipeline transportation slurry hydraulic calculation em- pirical formulas, and analyzed the application scope and advantages and disadvantages of these formulas, which provides the good reference for reasonable selecting the empirical formulas for coal preparation in- dustry.
