Measurements are presented of film flow rates, pressure gradients, film thicknesses, wave frequencies and velocities, and burnout heat fluxes in one annular and two tubular geometries. The more than 250 experiments were performed with steam-water at 30 to 90 bar under both adiabatic and diabatic conditions. On the basis of these data a film-flow model for the prediction of burnout is set up. General film roughness and entrainment correlations are derived from the adiabatic, equilibrium data. The capability of the model is demonstrated
by several comparisons between calculations and measurements.
