摘要
运用网格模型理论推导了低雷诺数、有颗粒浓度情况下空泡阻力系数的公式;由简单的相似原则和混合运动粘性系数概念,对单个空泡阻力系数进行修正,给出了大雷诺数范围内空泡阻力系数的公式。
Drag coefficient expression of air bubbles was induced by using multigrid rnodel at low renold number,the particle concentration has been taken into account Drag coefficient formulas at wide ranges of renold number were developed from simple similarity criteria and a mixtare viscosity model
