Abstract

The heat transfer and burnout phenomena at the depressurization from 3 kg/cm2a to the atmosphere were studied. Considering the initial subcooling, flow velocity and heat input as the parameters, the following results were obtained: The boiling heat transfer became very well during the process and then the situation stayed on the extension of the steady nucleate boiling characteristic curve until burnout inception. The burnout occurred at the higher heat flux than the steady burnout and did never occur at the first sudden vaporization just after rapid depressurization but it was delayed for a while (burnout time).
