Abstract
The paper discusses the results of experimental investigations of boiling heat transfer on sintered metal capillary-porous coverings of the heating surface. The experiments were carried out for copper, fibrous structures with stochastic distribution of pores. The boiling curves were obtained at the increasing and decreasing of the heat flux, which made it possible to detect the hysteresis phenomena of different types. The classification of the hysteresis phenomena, based on the author’s own results and those available in the literature, was provided. Three types of hysteresis were observed. The physical mechanism of the phenomenon was presented and the features characteristic of boiling in the porous covering was taken into account.
