Local and overall heat transfer around a pin finned tube in crossflow

Experiments have been carried out to investigate the local and overall heat transfer around a pin finned tube in crossflow of air. By employing 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 presented respectively. Finally, a correlation of the experimental data was obtained to calculate the total mean heat transfer coefficients of the pin fin tube.
