MEASUREMENTS OF BURNOUT CONDITIONS FOR FLOW OF BOILING WATER IN VERTICAL ROUND DUCTS

Technical Report ·
OSTI ID:4729910
The first phase of an experimental investigation of burnout conditions for flow of boiling water in vertical round ducts is reported. The results are presented in diagrams where, for a certain geometry, the burnout steam quality. x/ sub BO/, was plotted against the pressure with the surface heat flux as parameter. The data have been correlated by curves. The scatter of the data around the curves is iess than plus or minus 5%. In the ranges investigated the observed steam quality at burnout, x/sub BO/, generally decreases with increasing heat flux, increases with increasing pressure, and decreases with increasing mass velocity. The mass velocity effect has been explained on the basis of climbing film flow theory. For engineering purposes, the effects of inlet subcooling and channel length have been found to be negligible.
