Special features of steam-gas flow through a crack in the protective envelope of a nuclear power plant

Experimental data on the escape of steam and liquid drops with the outflow of a steam-air mixture through a model of a crack in a concrete protective envelope are presented.

Description
Summary:Experimental data on the escape of steam and liquid drops with the outflow of a steam-air mixture through a model of a crack in a concrete protective envelope are presented. The experiments are performed using cold and heated concrete assemblies. Complete condensation of the steam on the surface of a crack occurs at relatively low temperatures of the concrete assembly. As the concrete assembly is heated, drops appear in the gas flow at the exit.[PUBLICATION ABSTRACT]
