Resumo

This work experimentally investigates the combined effect of extended surfaces and vapour velocity during condensation of pure refrigerant on the outside of a single horizontal enhanced tube. More than 240 experimental runs were carried out over a wide operative range with two different fluids and three different tubes. Also the first results of an experimental investigation on a transparent test section are reported to analyse the fluid dynamic mechanism of condensation on extended tubes under high vapour velocity.
