Flow patterns during condensation of pure refrigerants on enhanced tubes under high vapour velocity.

Author(s) : CAVALLINI A., DORETTI L., LONGO G. A., ROSSETTO L.

Summary

This work experimentally investigates the effect of vapour velocity during condensation of a refrigerant on the outside of a single horizontal enhanced tube with particular reference to the fluid-dynamic mechanisms induced by vapour shear stress, surface tension and gravity on the condensate flow. More than 70 experimental runs were done in a transparent test section in order to observe directly the condensation of vapour, to take photographs and video-camera film, with two different extended tubes in a wide operative range.
