The critical heat flux under boiling and its dependence on the characteristics of heat-transfer wall

It has been experimentally found to date that boiling heat transfer is a problem with conjugate boundary conditions. Boiling heat transfer and critical heat fluxes depend both on the physical properties of boiling liquid and on a number of characteristics of the heat-transfer wall. In the present paper, experimental data of different authors are analyzed and an attempt is made at understanding the reasons for the significant deviation of the experimentally obtained values of critical heat flux from the values calculated by the available models of origination of crisis.
