A MODEL FOR CORRELATING TWO-PHASE, STEAM-WATER, BURNOUT HEAT-TRANSFER FLUXES
A simplified model for spray-annular flow in round tubes and rectangular channels and its use for the prediction of the maximum heat fluxes for steam- water flows is described. The data are for upward flow at 2000 psia for uniform and "hot-patch" heat fluxes. The model is successfully applied to both uniform and nonuniform or hot-patch heat-flux tests. Burnout flux versus flow rate data obtained for uniform heat flux for a given iniet subcooling are sufficient for the evaluation of the characteristic parameters needed in the burnout model. Comparisons of predicted and experimental values of the bumout heat flux are encouraging, including 2 to 1 hot-patch tests. Further, the predictions for the 1.3 to 1 hot-patch tests are in accord with the experimental data that the hot- patch effectiveness is approximately zero. (N.W.R.)
