The Institute of Thermophysics is one of the leading centers in the fundamental research field of turbulent heat and mass transfer under complex conditions. Investigations are being carried out in various directions for practical application in different industries: chemical technology, power engineering, and spacecraft technics.
    The asymptotic theory of a boundary layer was developed at the Institute. This theory allows one to calculate friction and heat transfer under perturbation factors (compression, injection, non-isothermal conditions, swirled flow, etc.) without additional empirical information. This theory has been experimentally proved, and is now being used for the development of physical models in different areas of the heat and mass transfer theory.
    Several automated thermal-gas-dynamic installations with modern measurement systems were created at the Institute. Methods for the gas-dynamic heat protection of surfaces from the effect of high-temperature gas flows are being studied at the Institute. These methods are of a great interest for modern power and machine engineering.
    In the field of boundary layers with physical-chemical transformations, transfer processes are being studied on surfaces with evaporation and condensation, accompanied by heterogeneous chemical reactions, and in a boundary layer with a combustion front.
    Methods for the numerical calculation of turbulent combustion are being developed using different models of turbulence and chemical kinetics.
    Experimental investigations of heat and mass transfer in the detachment and high-turbulent flows are of a particular interest. Mechanisms of turbulent heat and mass transfer are being studied in the detachment zones behind large obstacles, in the two and three-dimensional cavities, and in the near-wall concurrent and countercurrent jets for subsonic and ultrasonic flow regimes.
    In the field of free-convective flows, the following are being studied: heat transfer through flat liquid layers with various orientations, and heat transfer from vertical walls, horizontal discs, and other revolving bodies with a temperature different from the ambient one. These investigations have been carried out in modes of thermal-gravitation, heat gravitation-capillary, and mixed (boundaries rotating in a non-isothermal system) convection. These studies are focused on the relationship between integral heat transfer and the peculiarities of the flow structure caused by a laminar-turbulent transition with an increase in Rayleigh, Reynolds, and Marangoni numbers.
    Radiation heat transfer is predominantly of a theoretical character.
    A theory for integral, differential, and algebraic radiation equations was developed for the description of the energy transfer process in complex media. Radiation heat transfer in moving media with volumetric absorption, radiation and scattering is being studied using numerical simulation of boundary problems. These problems describe the heat and mass transfer processes in laminar and turbulent boundary layers, on a sheet and in a cylindrical channel, regarding the real optical properties of gases, plasma, and streamlined boundaries. The multiparametrical relationship between radiation and convection processes has been revealed.
    This relationship excludes the use of additive calculations. Studies of radiation-conductive heat transfer in optically non-uniform laminar and dispersible radiation media are being continued in the cases of phase transitions and cooperation effects. Also, in the conjugate task these studies were continued for radiation-convective heat transfer in boundary layers during chemical reactions and diffusion processes in conjunction areas.
