BASIC EXPERIMENTAL STUDIES OF BOILING FLUID FLOW AND HEAT TRANSFER AT ELEVATED PRESSURES. BiMonthly Progress Report, January-February 1964

Technical Report ·
OSTI ID:4040392
Nineteen instrumented burnout poirts are reported for the 3-tube test section which consisted of three identical heated channels (0.495 in. ID and 87.9 in. heated length) connected to common inlet and outiet headers operating with vertical upflow at 1500 psia. The ranges of variables covered were: mass velocities from 1.1 to 4.2 x 10/sup 6/ lb/ hr-ft/sup 2/, exit qualities from -- 2.3 to 32.6% and heat fluxes as high as 1.2 x 10/sup 6/ Btu/hr-ft/sup 2/. These burnout data are slightiy lower (0--10%) than results for a single tube of similar dimensions. No evidence of hydraulic instability was found even when the test section was operated with a large unheated bypass flow. (auth)
