| 摘 要： | 浆体的流动阻力是浆体输送管道设计的重要参数,其大小直接影响到输送的费用.因此研究不同流态下浆体的流动阻力机理并采用适当的减阻技术具有非常重要的意义.在总结国内外对管道中浆体流动状态分析的基础上,对完全分层和完全混合两种流动状态下的阻力机理进行了探讨;针对影响浆体流动阻力的影响因素,对适当粒径级配减阻、减阻剂减阻、升温减阻等减阻技术做出了分析总结.

| Abstract: | The resistance of slurry in pipelines is an important parameter in designing a slurry-conveying pipeline,whose size affects the cost of transportation of slurry.Therefore,it is of great importance to study the resistance mechanisms and adopt proper technologies in reducing the resistance of slurry in pipelines.Resistance mechanisms of both fully stratified flow and fully suspended flow were discussed on the basis of analyzing the flow state of slurry in pipelines both at home and abroad.Considering the influential factors on resistance of slurry in pipelines,technologies of reducing the resistance by adjusting the sizes of particles,adding resistance reducers and raising temperatures were summarized. |
