Heat transfer crisis on porous surfaces - experimental investigations and the outline of the maximum point process based model

The paper presented the results of experimental investigations into intralayer boiling crisis and accompanying phenomena. It was observed that the structural parameters of the porous covering affected the course of the process. Hysteresis phenomenon manifested itself when the heat flux initiating intralayer heat crisis was reached. The crisis mechanism hypotheses, the description of which was available in literature, were discussed. The maximum point process was selected as a tool of the mechanism modelling. There was presented the methodology of the calculations of intralayer boiling crisis occurrence probability which depends on physical and chemical properties of the surface and the liquid as well as the porous structure geometrical properties.
