Abstract: A review discusses current status of boiling heat transfer research. Basic experimental facts, physical models
and correlations of experimental data on heat transfer coefficient (HTC) are reconsidered. Principal restrictions of
traditional model of “the theatre of actors”(MTA) are demonstrated. Basic role of control of HTC by thermodynamic
conditions on nucleation sites is demonstrated and consequent model of “the theatre of director”(MTD) is discussed.
Universal MTD-based correlation of boiling HTC of all types of liquids is presented. Unified consistent research
framework for developed boiling heat transfer and diverse specific boiling heat transfer regimes is outlined through
supplementing MTD by so-called multifactoring concept (MFC). MFC links transition from developed boiling mode to
diverse boiling curves to a phenomenon of multiplication of factors influencing HTC. Multifactoring phenomenon equally
can cover any boiling process including boiling in minichannels and microchannels. Possible types of multifactoring are
considered. Finally, the ways of further research of the boiling problem are discussed.
