Enhanced film condensation heat transfer of methane vapour.

Author(s) : WANG R. S., LU X. S., GU A. Z., ZHANG L., ZHOU C.

Summary

An experimental apparatus is built to observe performance of laminar film condensation of methane vapour. The experiment is carried out using V-longitudinal grooved tubes. The condensation heat transfer coefficient of V-longitudinal groove tube is 3-8 times larger than that obtained with the smooth surface. In order to explain the heat transfer enhancement of the condensing surface, a mathematical model is proposed for studying condensation characteristics along V-longitudinal grooved tubes; the maximum deviation between the predicted values and the experimental data is 15%.
