Abstract

The burnout mechanism has been studied by investigating the effect of nonuniform heat flux distribution along the channel length and determining local characteristics of a two-phase flow. The experiments on the sections with various form factors at 2. 9-16. 7 MN/m**2 and 750-3000 kg/m**2s have revealed the effect of nonuniform heating on burnout. The physical model explaining this phenomenon has been proposed. The air- and steam-water high pressure flow patterns in channels were studied by optical pulse holography. Special equipment and double-beam optical holographic schemes have been developed. A possibility to apply holography for this purpose has been shown. The photographs of 3-dimensional images of various two-phase flow patterns reconstructed from the holograms are presented.
