Structure Optimization of Dual Impellers in Solid-Liquid System by Numerical Simulation

  • 摘要: 应用多重参考系法以及欧拉多相流模型,对双层搅拌釜内固液两相流进行CFD数值模拟,考察了不同桨叶组合形式及其安放角(θ)对固体颗粒悬浮以及功率消耗的影响。结果表明:在双层下压式斜桨中,上下层桨叶间的协同作用可以有效促进主体循环流动,提高釜内整体湍动程度,改善颗粒悬浮状况;安放角对釜内整体流型无明显影响,但体系的轴向速度、湍动能以及功率消耗都随着θ的增大而增大,其中θ为45°时可以适宜的功率获得较强的轴向流动和湍流脉动,有利于实现固体在釜内的均匀分布。
