DESIGN CURVES FOR BURNOUT HEAT FLUX IN FORCED-CONVECTION SUBCOOLED LIGHT-WATER SYSTEMS

摘要

Design (minimum) values of burnout heat flux for subcooled water systems were calculated with the writer's superposition correlation. The calculated fluxes were not reduced with an arbitrary design factor;instead, each term was modified to coincide with the lower bound of avail-able experimental data — i.e., established scatter limits were applied to each factor separately. Burnout fluxes were plotted for 10 < V < 100 fps, 15 < P < 3000 psia, 100 < △tsub < 400°F, and channel equivalent diameters of 0.1 and 0.5 in.nIn addition, a simple method is described for estimating the ratio of burnout to incipient-boiling heat fluxes. The method is applied to the HFIR to indicate the dependence of the subject flux ratio on velocity, subcooling, and pressure.
