RÉSUMÉ

In the paper, a theoretical model of the boiling crisis at high vapor quality is modified from the earlier version presented by Sedler and Mikielewicz [1]. The model employs the analysis of the film dryout process on the wall which allows formulation of the differential equations of liquid mass balance in the film and the core. The solution of these equations contains the parameters which are determined experimentally in the paper since theoretical determination of them involves serious difficulties. The relations for determination of deposition and entrainment rate are taken from [2].
