Experimental research was conducted on a heat-emission crisis when water is boiling in vertical tubes with one closed end. This crisis is the result of a hydrodynamic crisis (''flooding'') of steam-water counterflows, which leads to a reduction in the flow rate of the downward-flowing water in the channel. An equation is given for determining the time interval between the moment that flooding starts until the moment that the surface temperature of the heat-generating channel begins to rise. A calculated function for determining the critical thermal flux is given and is compared with experimental data.
