Heat and Mass Transfer
The effect of the law and temp of the heat load's increase was studied together with the heater's time lag, and pressure reduced by a value of the critical heat flux.
The stability and development of one and two-dimensional sites of film boiling are being investigated. Criteria which characterize the boundary conditions at the front of changing boiling regimes are determined depending on the thermophysical and geometrical parameters of the heat-liberating surface. The studying of heat transfer and hydrodynamics during heating, evaporation, boiling, and the heat transfer crisis in flowing liquid films is in progress.

Thermocapillary convection, underheating, and the heaters' sizes are being investigated. Experiments are being carried out using a wide range of fluids such as water, ethanol, freons, nitrogen, carbon perfluorates, and their mixtures. A phenomenon of horizontal standing wave was determined during the evaporation of a downward liquid film flow underheated lower than the saturation temperature.
Calculation dependencies for the critical heat flux in flowing films of saturated liquid arebeing obtained for different ranges of the changing Weber number. The modeling of interconnected heat and substance transfers in two-phase multicomponent systems is one of the investigation directions. The main peculiarity of these systems is mass transfer from one phase to another, accompanied by the great release or absorption of heat.
Precise analytical solutions are being obtained in the framework of the developed models for one of the above processes of vapor or gas absorption by liquids.
These solutions are used for the calculation of efficient absorption apparatus including heat pumps and refrigerators. The study condensation of vapor film. A unique complex of large-scaled setups has been developed at the Institute for the study of heat and mass transfer in two-phase systems. Gogonin I.
