Abstract
Experiments were carried out to study the heat transfer performance of a heated circular cylinder in turbulent pulsating crossflows. For a single heated circular cylinder, heat transfer enhancement factors up to 1.26 were observed in the studied parameter range. Two empirical correlations with different deviations were developed. The heat transfer enhancement factor was found to decrease with Strouhal number and Reynolds number, but increase in trend with the ratio of pulsating to steady Reynolds number.
