摘要：

Experiments have been performed to investigate the heat transfer characteristics of a tube with elliptic pin fins in crossflow of air. By means of the heat/mass transfer analogy and the naphthalene sublimation technique, the local-heat transfer coefficients on pin fins and on the tube surface have been measured respectively. Correlations of the experimental data Were obtained. to, calculate the total mean heat transfer. coefficients. Experimental results show that the tube with elliptic pin fins has higher heat transfer coefficients than those of a smooth circular tube.
