BURN-OUT ANALYSIS. PART I. A BURN-OUT CORRELATION FOR WATER IN ROUND AND RECTANGULAR CHANNELS UNIFORMLY HEATED AT VARIOUS PRESSURES WITH FORCED CONVECTION

Technical Report ·
OSTI ID:4786418
The practical objective of research on burn-out is a reliable method giving the maximum safe rating for any water cooled reactor. Experimental work, which began at numerous centers about 10 years ago, was concerned principally with endeavoring to understand the phenomenon as it applies to simple geometries such as round and rectangular channels. This considerable effort has achieved little real success in providing an explanation of 'burn-out' however. While some uncertainty may be due to experimental variations, inadequate analytical effort is considered to be the primary cause of the present confused situation. The result of some work already carried out is described. An initial examination made on a large group of burn-out data is described and the development is reported of a correlation which predicts burn-out heat fluxes to within an R.M.S. error of less than 10% over a wide range of operating conditions including pressure.
