The industrial conversion to new alternative refrigerants is now one o
f the major driving forces in two-phase flow and boiling heat transfer
research. A state-of-the-art review is presented here to quantify wha
t has been done so far, assess the strengths and weaknesses in current
boiling correlations and two-phase flow pattern maps, and identify fu
ture research requirements and objectives. Copyright (C) 1996 Elsevier
