Abstract
The existing methods of estimating the stability of boiling modes to finite deviations are analyzed. The Lyapunov direct method for distributed systems is used to formulate the variational principle. The value of the functional is used as the measure of stability. Stability diagrams are suggested which enable one to judge the level of their stability by the arrangement of the boiling modes relative to one another. The dependence of the critical heat flux and critical temperature difference on the value of random deviation of the heating wall temperature is described using threshold curves. The correlation between the rate of propagation of temperature waves and the functional increment is found.
