摘　　要：通过实验研究了航空煤油在内径为1mm的微小圆管内的传热情况。实验压力范围为:(673～741)KPa,流体平均温度范围为:(43.9～109.5)℃,流速为:4m/s,实验管内径为1mm,外径为2mm,管长为360mm,实验结果表明:在该实验范围内,在内径为1mm的微小圆管内,航空煤油的传热规律和常规尺度圆管中传热经典公式相吻合。Experiment has been done to investigate the heat transfer of the kerosene in micro tube. In the test,the pressure ranges from 673KPa to 741KPa;the average of the fluid temperature ：43.9-109.5; the fluid velocity is 4m/s,the test tube is 360mms long,with the inner diameter of lmm and outer diameter of 2mm. the result shows：in the conditions of the test,in the micro tube with inner diameter of 1mm,the heat transfer law of the kerosene agrees with the traditional correlation.

关 键 词：微小圆管内 传热规律 经典公式 吻合
