Abstract
The problem of the thermal status of the noise- and heat-insulating housing (NHH) of a gas-turbine plant (GTP) is examined. Results are presented for an investigation of the thermal status of the space beneath the NHH and its walls with allowance for heat transfer due to radiative emission of heated components of the structure. A mathematical model is proposed for calculation of the air current within the NHH, and the temperature of the air and material of the housing at each point of the computational domain with consideration of radiation heat exchange. It follows from analyses of the NHH of one of the gas-pumping units that the maximum temperature (+50°C) of the outer surface of the walls of the NHH is attained in the region of the scroll of the GTP.
