Abstract
The aim of the paper is to supply updated air convective coefficients by means hα of three empirical correlations set forth by Zukauskas, Churchill and Hilpert for cylindrical bodies in cross-flow. In this study, low Reynolds numbers and air velocities within the range of were considered, hence, sundry values of convective coefficients were obtained and applied in a lumped heat capacity model. Finite element analysis simulations were implemented, exhibiting good conformity based on these correlations. The findings show that among the three methodologies, Zukauskas's correlation presents minimum standard deviation sd = 0.02 and the maximum standard deviation is presented by Hilpert's correlation sd = 1.92, Churchill correlation presents a standard deviation of sd = 0.3. The results are reliable and can therefore be used for analyzing heat convection.
