【摘要】 本文试验研究了水煤浆在管道输送过程中的非稳定流动特性，包括突然启动特性、缓慢启动特性及流量突然变化时的输送特性，并试验研究了水煤浆在管道内的滞留时间对启动压力的影响，为实际水煤浆管道输送系统的工程设计提供了设计参数。更多还原

【Abstract】 The characteristics of Coal-Water Slurry (CWS) unsteady flow in different conditions suchas sudden start-up, slowly start-up, sudden change of CWS flow rate are studied experimentally. Theeffect of stagnant time of CWS in the pipeline on the starting pressure drop is also investigated, whichwould contribute necessary parameters to engineering design of CWS pipeline transPOrtation system.更多还原
