THERMAL REGIMES OF THE WORK ZONES OF PRODUCTION FLOOR AREAS UNDER THE CONDITIONS OF LOCAL HEATING AND HEAT DISSIPATION THROUGH AN UPPER BOUNDARY

摘要

Results of numerical modeling of the process of free-convective heat transfer in a turbulent convection regime in a rectangular enclosure heated by an infrared gas radiator are presented. A comparative analysis of two alternative locations of the infrared gas radiators in modeling of typical free-convective heat transfer regimes in the region is conducted. The essential nonstationary nature of the heat-transfer process and the influence of heat emission from the surface of the upper horizontal filler structure on the temperature patterns of zones of local heating of large work zones are established.
