Condensation of a vapour with incondensables: an improved gas phase film model accounting for the effect of mass transfer on film thickness.
Résumé
An improved gas phase film model is presented for calculation of local skin friction, heat and mass transfer coefficients in condensers. The model account for the effect of local mass transfer intensity on film thickness in turbulent flow. Predictions from the proposed model and from the classical film theory and condensation curve method are compared with experimental data for a saturated steam.
