Gyrman L. Thermotechnical peculiarities of filler structures with dead air spaces

The object-enclosure of the building with a closed air layer; goal - improving thermal (operational) quality walling with air layer, methods - physical and mathematical modeling, analytical methods based on the laws of technical thermodynamics of radiation and convective heat transfer, thermal conductivity, novelty - the problem is formulated and the resulting system of equations (mathematical model) that describes the process of heat transfer in building envelope design with a closed air layer obtained mathematical model can determine the velocity of the air in the air layer, to analyze the ratio of convective and radiant heat fluxes, and determine how other factors affecting the processes of heat transfer, based on a mathematical model developed by more modern methods of calculating heat transfer processes in the closed air layer and determination of resistance to heat air layer, developed recommendations for improvement of performance walling with a closed air layer, the results - the design-convection solar dryers and design of windows with variable heat transfer coefficient; the field is Building.
