Analysis of Airflow Field in Bearing Chamber Considering Droplet Motion Impact

  • 摘要: 航空发动机轴承腔中考虑油滴运动的气相物理场分析是进行二次流及润滑系统设计的基础工作。因此,采用有限元数值分析的方法,研究了轴承腔中嵌入油滴运动影响条件下气相介质的速度场、温度场和压力场,并探讨了转子转速对气相介质流动速度、温度以及轴承腔连通区域压力分布的影响规律。分析结果表明:随着转子转速的增大,气相介质流动速度和温度增大,同时进气腔与回油腔之间压力差减小。此外,将考虑油滴运动的气相物理场与油滴/空气相的耦合计算方法所得结果进行对比,据此确定本文所采用研究方法的准确性及其在计算时间上的优势。
