Several properties of mathematical models

There is considered the problem of thermal conditions in noise and heat protective housing where gas turbine plant is located. There is marked in the article that in the process of investigation of thermal conditions in its walls the attention should be paid to the heat transfer owing to the radiation of heated elements of a housing. There is proposed the mathematical model which permits to calculate the air flow inside noise and heat protective housing and air temperature, as well as, temperature of noise and heat protective housing material in every points of design range considering radiation heat exchange. There were made calculations for an noise and heat protective housing of one of gascompressor unit. The satisfactory convergence in calculated and experimental temperature values of noise and heat protective housing outer walls was received.
