Abstract

The experiment was conducted to obtain correlation of the air side heat transfer coefficient of wire-on-tube type heat exchanger using the single layer heat exchanger. The correction factors to Zhukauskas correlation was driven from the experimental results. The numerical analysis and experiment with several wire-on-tube type condensers to validate the correction factors are also peformed. The maximum discrepancy between experimental results and the numerical results using the correction factors of this study and Zhukauskas correlation is 10.0%, while that of reference correlation is 47.5%.
