Abstract
The results of a numerical analysis of the parameters of the system of radiative heating of an open platform, a flat car of size 10 × 75 m, are presented. The temperature of the radiator of size 0.3 × 9 m was 600–900 K. The temperature of the atmospheric air varied in the range from –10 to +10°C at a wind velocity of up to 5 m/s. As the criterion of heating comfortably a human being, the temperature at the level of his head (175 cm) was taken. As a result of the computational experiment, the dependences of the temperature of the heated platform on the temperature and the height of the radiator mounting, as well as on the direction and velocity of wind, were obtained. It has been established that the temperature at the level of the top of the human being’s head is equal from 2–3 to 16–18°C when the radiators are disposed at a height of 4–8 m from the platform surface at the surrounding air temperature of 0°C and wind velocity of 0.5–5 m/s. It is shown that on decrease of the air temperature to –10°C the installation of wind protection is required.
