Suggested method for heat transfer calculation during film condensation inside pipes with movable frontiers

Abstract

This paper provides a second evaluation, with the intention of formulating an improved model that is capable of predicting the mean coefficients of heat transfer during condensation inside tubes with any orientation. This model has been developed through the application of transportable borders for the propagation of heat inside an elementary volume, up to the macro system considered. The theoretical model obtained leads to two basic dimensionless groups, which establish the study intervals that should be considered in the correlation of experimental quantities available, for the development of future experimental models.
