BASIC EXPERIMENTAL STUDIES OF BOILING FLUID FLOW AND HEAT TRANSFER AT ELEVATED PRESSURES. Monthly Progress Report, June 1963

OSTI ID:4684070
The data previously obtained for burnout inside large diameter tubes (1.475'', 0.930'' and 0.504'') at 1000 psia are replotted to show the effect of diameter on burnout heat flux. The results show that above a mass velocity of 2.8 x ractically no effect of diameter on burnout heat flux. As the mass velocity is decreased below 2.8 x 10/sup 6/s lb/hr-ft/sup 2/ there is an increasingly strong reduction in burnout heat flux as the diameter is increased at constant exit steam quality. The above data for tubes with a heated length of about 77" are also compared to the data from a 0.930" ID tube with a 24" heated length. It is shown that at a constant exit quality burnout heat flux decreases with increasing length and that the effect is less pronounced with increasing mass velocity. (auth)
