Investigation of mixed convection of supercritical pressure RP-3 in vertical round tube

  • 摘要: 研究了超临界压力下碳氢燃料航空煤油RP-3在竖直细圆管内混合对流,分析了浮升力及热物性对碳氢燃料在垂直管中对流换热的影响。实验中控制热流密度从200~500 kW/m2变化,进口压力变化范围为3~5 MPa,进口雷诺数从5 000~10 500范围内变化。研究表明:在向上流动情况中进口段存在较为明显的入口效应,换热出现恶化现象,而在向下流动中未出现;对于向上和向下流动,由于热物性的综合影响,换热系数沿流动方向增大;在较低进口雷诺数(Re=5 700)时,对于向下流动,随着浮升力影响的增大,浮升力改变了流体径向速度分布,出现了换热强化;在较高进口雷诺数(Re=10 500)时,浮升力对换热的影响依然显著;判别式Bo*数小于5.6×10-7未能预测浮升力对碳氢燃料换热影响。
