Abstract

Experimental data of the condensate film thickness and the heat transfer coefficient during condensation of steam inside a tube are presented over a range of the film Reynolds number from 500 to 5000 and are compared with the analytical predictions for turbulent and laminar film condensation. Based on the data obtained, the thermal laminar sublayer thickness of condensate film is investigated. The results indicate that the laminar sublayer thickness is different from that of single phase full tube flow.
