INVESTIGATION OF BURNOUT HEAT FLUX IN RECTANGULAR CHANNELS AT 2000 PSIA
Burnout heat flux data were obtained under conditions of zero exit quality and bulk boiling at the exit of electrically heated test specimens. These specimens were long, narrow channels with various slot thicknesses, sunfaces, materials, and length-to-diameter ratios. Tests were run at 2000 psia and mass velocities from --0.2 x 10/sup 6/ to 3 x deg was also investigated. The rectangular channel burnout results are in reasonable agreement with data previously obtained for round tubes. A design equation is suggested which yields a conservative estimate of the burnout heat flux in the low subcooling and quality regions. A burnout loop and method of operation are described. (auth)
