A REVIEW OF DATA ON BURNOUT HEAT FLUX FOR STEAM-WATER MIXTURES IN UNIFORMLY HEATED CHANNELS
A discussion is given of the available methods of predicting burnout heat flux in systems containing flowing mixtures of steam and water. The reliability of the methods when applied to experimental information obtained from uniformly heated round tubes, rectangular channels, and annular passages is reviewed, and the variables which influence two-phase burnout are considered with a view to explaining observed trends. It is concluded that a direct experimental study is required before confident prediction of burnout heat flux in divided fuel elements of the rod cluster type will become possible, and that sufficient information does not exist for general extrapolation of results obtained from simple geometries to such a case. Until further data become available it is suggested that a simple correlation, based only on the major variable, exit quality, should be used to calculate burnout heat flux in rod-cluster fuel elements cooled by steam-- water mixtures at pressures of 1000 psia.
