MATHEMATICAL MODELING OF AIR FLOW IN ROOMS TAKING INTO ACCOUNT SOLAR RADIATION

The article is devoted to the computational studies of the air flow in the of office rooms taking into account the effect of solar radiation coming through window openings. The study was conducted for a room with two windows using two heating devices installed under them. The air regime of rooms in winter; characterized by the highest thermal energy consumption for heat supply; is considered. The study is based on the solution of a three-dimensional nonlinear heat transfer problem described by a system of equations of turbulent momentum and energy transfer. The k-ε turbulence model is used to close this system. The results of numerical modeling of the physical situation under study are presented. The research data on the features of the air state of the rooms under solar radiation conditions are given.
