Jones, Jr, O C

Recent work aimed at correctly describing nonequilibrium vapor generation rates in flashing liquids in decompressing flows similar to those which might be encountered in a loss of coolant accident in a nuclear reactor is summarized. Analysis is reviewed which describes the flashing inception superheat in terms of the turbulence intensity for a given expansion rate and initial temperature, and interfacial area density and interfacial heat flux, and the volumetric vapor generation rates. Comparisons with existing data are included and further experiments being undertaken are described, including typical recent results.
