“…This procedure allowing also reducing the uncertainty index up to 13 % for vertical and inclined tubes, while for horizontal tubes the average error is reduced up to 11.8 %. Table 2 offers a comparison of the index of correlation obtained when compare the experimental available data with the obtained results by means of the uses of a group of existing models in literature [15,21]. When verifying the given results, it could be verified that the proposed model evidences better values of adjustment, with an average error of the 15 %.…”

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.

Numerical investigation on entropy generation in the dropwise condensation inside an inclined pipe

In this paper, the entropy generation analysis in dropwise condensation in an inclined pipe is carried out. As the vapor passes through the inclined pipe, the flow of the droplets occurs due to the interfacial shear and gravity. Three distinct zones considered in the numerical study include the saturated vapor flowing in the axial direction, saturated liquid traveling through the bottom of the pipe, and the condensate droplet flowing on the inner side of the pipe wall. With the aim of achieving optimal geometrical conditions of the pipe and flow, the entropy generation was calculated for various cases. The results show that the minimum entropy generation of 0.0754 W•K −1 occurs in a configuration with a diameter of 9.5 mm and an inclination angle of 1°. Finally, the Bejan number, irreversibility distribution ratio, and variation according to the flow conditions were presented.
