Abstract
The results of mathematical modelling of aerodynamic thermal processes in the rooms are presented for several schemes of the air supply and removal. The model rooms having the shape of a cube are considered, inside which there are or there are no obstacles and heat sources. The equations of a steady three-dimensional isothermal or non-isothermal gas motion corresponding to the k-ε- turbulence model are used to describe the thermal and aerodynamic processes. The similarity criteria are found for the processes of the heat and air exchange. Basing on them, a detailed numerical investigation of the influence of determining parameters of the problem on the local and averaged characteristics of the velocity and temperature fields has been carried out.
