【摘要】 为解决煤矿新型超高水填充浆料的井下400 m混合问题,采用固液两相流理论与计算流体力学(CFD)方法,建立填充浆料在混合器中的流动控制方程;采用三维软件(UG)建立模型,并导入GAMBIT进行混合器的三维网格划分,在FLUENT中的3D单精度解算器中进行数值模拟。通过分析静态混合器中各截面的流动状态,获得静态混合器在既定条件下的最佳长度和浆料的出口速度。更多还原

【Abstract】 In order to solve 400 m underground mixed problem of new superhigh-water packing material in Coal Mines, solid-liquid two-phase flow theory and computational fluid dynamics(CFD)method were used. Flow control equations of packing slurry were established. Mixer model was established through 3d software(UG) and imported to GAMBIT for 3d meshing. Numerical simulation was conducted in the 3D single precision solver of FLUENT. The optimum length and exit velocity of slurry were acquired through analyzing flow state of sections in the static mixer.更多还原
