Abstract
The problem of initiation of transition from nucleate to film boiling regime is considered from two statements: stationary and dynamic ones. Analysis of stationary problem allowed determination of relationship between heat load and critical size of a film domain. According to investigation of development dynamics of boiling crisis, at local deterioration in heat transfer, there is some critical size of a film domain, which is determined by a heat load and duration of initiating action. Whereas, at a local temperature increase, the critical conditions are determined only by the amplitude of temperature perturbation and heat power.
