【摘要】 讨论和分析了高浓度水煤浆的管内流动特性,阐述了影响水煤浆流动特性的若干因素,综述了水煤浆管内流动阻力特性的理论和计算方法。在分析探讨水煤浆“滑移层”的机理及其对管内流动影响和修正的基础上,介绍了表征水煤浆流动状态的相似准则数——广义雷诺数,可以应用于工程上的简化计算。更多还原

【Abstract】 The flow properties of high concentration coal-water slurry(CWS) were thoroughly discussed along with some impactive factors.The theoretical analysis and calculation method to the drag force in pipe flows of CWS were summarized.Based on mechanism of the slip layer,its influence and modification to the flow structures,an extended Reynolds number Reg was proposed which can describe the CWS flows and can be used into the engineering calculations.更多还原
