Radiative-Convective Heat Exchange of a Building with the Environment on Exposure to Solar Radiation

The results of computational investigations of the aerodynamics of a building located in the urban area with a high density of buildings and of its heat exchange with the environment are presented. A three-dimensional numerical model of nonstationary processes of transfer of momentum and heat on interaction of the building with the wind under the conditions of diurnal variations of the solar radiation intensity and air temperature has been constructed. The model allows one to estimate the basic parameters of the heat exchange of the building with the environment under different seasonal conditions.
