摘要
包钢白云鄂博输送矿浆管道弯管磨损比较严重。应用Fluent软件,模拟矿浆流动在管道内部的流场分布,对比分析了1.2 m/s和2 m/s矿浆流动初速度的压力、壁面剪切应力和磨损分布图。研究结果表明:对于压力场,由于离心力的作用,外侧压力高于内侧;由于受重力的影响,壁面剪切应力场是弯管内侧高于外侧。为矿浆管道的流体输送提供了理论依据。
The bend wear of Baotou iron and steel company to Bayan Obo was relatively severe.Use Fluent software to simulate the distribution of mine slurry flows inside,then analysis the pressure and wall shear stress distribution diagrams of velocity's initial flow in 1.2 m/s and 2 m/s. The result shows:for the pressure field, due to the effect of centrifugal force, the lateral pressure is higher than that inside;in the influence of gravity that the wall shear stress distribution of pipe bend inside is higher than that outside. What have done will provide theoretical basis for the fluid transport of mine slurry.
