Abstract

An experimental investigation on heat transfer performance of enhanced tubes is conducted with refrigerant R134a. The heat flux is from 10,000 to 370,000 W/m². The heat transfer is substantially enhanced at the heat flux less than 200kW/m². An increase of heat transfer coefficient up to 330% above the plain tube is observed. However, at the heat flux higher than 200kW/m², it is found that the heat transfer coefficient of enhanced tubes is even lower than the plain tube. The same features are also observed for other enhanced tubes in the literatures.
