| 摘 要： | 为探索一种适于模拟轴承腔油气两相流流动特性的数值计算模型,建立了一套简化结构的轴承腔试验装置,通过试验研究获得了不同工况对轴承腔通风口出气比例和回油口滑油温升的影响规律.应用Fluent软件,采用Mixture多相流模型和Eulerian多相流模型分别搭配标准k-ε湍流模型和RNG(renormalization group) k-ε湍流模型对选定试验工况进行数值模拟.对比结果表明:当转速为2 200 r/min时,使用Mixture多相流模型搭配RNG k-ε湍流模型计算的滑油温升与试验值的相对误差仅为2.72％,体现了该计算模型在高转速时的精确性,并在此基础上获得了油气两相流速度场、压力场和温度场的分布特征.
