Improvement on one-dimensional flow model of rotor-stator cavity with central inlet

  • 摘要: 采用数值模拟方法,对动盘面边界层夹带流量进行分析,以改进转静盘腔一维流动模型的计算精度.结果表明:边界层速度分布的1/7幂律假设低估了自由盘边界层夹带流量,从而影响了一维流动模型对源区边界的计算精度;传统的关联式未能有效地归纳不同工况下转静盘腔内动盘面边界层夹带流量,从而影响了一维流动模型对核心区气体转速的计算.通过归纳数值模拟结果中的自由盘和转静盘腔内动盘面边界层夹带流量,对传统一维流动模型中源区边界及核心区气体转速的计算提出修正,并对修正后的一维流动模型进行实验验证,表明该修正明显改进了一维模型对腔内径向压差的计算精度.
