Summary

The model basically follows the smooth tube correlation proposed by Haraguchi et al. (1994), in which the total condensation coefficient is composed of the contributions of film condensation and forced convective condensation. For the microfin tube, the film condensation term is estimated from the product of total unflooded area and local enhancement factor, while the heat transfer coefficient of forced convective condensation is set equal to that of the smooth tube. The predicted results show good agreement with experimental results.
