摘要
以汽油-空气为介质,在不凝性气体质量含量不超过5%时,对导程为200mm的螺旋扁管管束中的沸腾换热进行了实验研究,分析了沸腾换热系数随两相质量流量的变化规律以及流动压降随空气流量的变化规律。得到了相应条件下,载气汽油在该导程的螺旋扁管管束中的沸腾换热实验关联式。
An experimental investigation on boiling heat transfer of gasoline-air mixtures in spiral-flat tubes of 200mm-pitch was carried out,while the content of incondensable gas is less than 5%.The result shows that while the content of incondensable gas increases,the bubble point temperature of gasoline decreases and the flow pressure drop increases.And the boiling heat transfer coefficient experimental correlation was established.
