Heat transfer and voidage measurements in steady state post-dryout at low quality and high pressure

Steady state post-dryout heat transfer and voidage data have been obtained at pressures up to 70 bar and flows up to 1000 kg/m2s inside a vertical tube. The data were obtained with steam/water using a directly heated hot notch test section. Heat flux and voidage data are presented. The data are used to investigate aspects of the TRAC-PF1/MOD2 version 5.3 reflood model and are compared against heat transfer models used in it. (8 figures) (Author)
