Abstract

A three-dimensional unsteady model of filmwise vapor condensation on a curved surface that takes into account the mass forces, the surface tension, and the friction on the surface of the condensate film is developed. This model generalizes the previous models of the filmwise vapor condensation. An evolution equation is derived for a condensate-layer thickness. Numerical algorithms are developed for solving the evolution equation. The condensation of ethanol vapor moving in a round tube is calculated. The effect of the tube diameter on the intensity of condensation is analyzed.
