Summary

Ten times higher heat transfer can be achieved with two-phase flows in compact heat-exchanger compared to conventional circular tube exchangers. Research on evaporation in smooth circular and non circular channels, as well as low velocity flow boiling in confined spaces is also reviewied in relation to phenomena occuring in compact heat exchangers. In particular, the effects of channel geometry/size, fin type, gravity and heat transfer mechanisms are highlighted. Finally, specific recommendations are made for future research.
