Abstract :
In an approximation of a turbulent boundary layer on an exterior surface of window glass, the heat exchange in conjugate statement is considered. The algorithm of computation is developed, the program is composed and numerical simulation of processes of nonstationary radiative-conductive and radiative-convective heat exchange is carried in a boundary layer on the outside surface of the glass. Thus the thermal state (field of temperatures and fluxes) of a plate and boundary layer, its dependence on intensity of solar radiation and environment, radiative and convective heat supply to glass from the room, overfall of average temperatures of the room and environment, velocity of blowing by air of an exterior surface of glass, etc. are analyzed. The essential role of forced convection and expediency of window screening is shown
