Original Abstract

This paper presents a theoretical study focused on the possible enhancement of the heat transfer in a vertical tube during condensation of steam. Two different concepts of condenser operation are compared. The first concept considers a condenser pipe with steam inside and coolant flowing along the external pipe wall. The second concept considers steam inside the pipe and the coolant flowing along the inner wall together with the steam. During the condensation process, a liquid film is formed on the pipe wall. This fluid film represents a thermal resistance that increases with the increasing thickness of the film. The operating parameters of both considered concepts are compared with the utilising of a developed analytical procedure. The analytical model is focused on the detail evaluation of the liquid film parameters on the heat flux, intensity of the condensation process and output temperature of coolant leaving the condenser.
