人们对于圆管两相流水力计算作过很多的探索,但是由于影响两相流的因素很多,问题比较复杂,对其阻力本质尚没有研究透彻。不能从理论上推导出成功的计算公式。目前设计科研部门在进行水力计算时,只能应用一些经验公式。我国有色矿山的尾矿输送很多都是采用压力水力输送,由于这些公式本身的局限性,其结果必然与生产实践有出入,这种出入
However, due to the many factors that affect the two-phase flow, the problems are complex and the nature of the resistance has not been thoroughly studied. Can not theoretically derive the successful formula. At present, the design and research departments in the hydraulic calculation, can only apply some empirical formula. Due to the limitations of these formulas, many of the tailings transportation of nonferrous mines in our country are carried out by hydraulic and hydraulic conveying. The result is necessarily different from the production practice.
