Numerical analysis of an engineering structure effect on a heat loss of channel-free heat pipeline

The results of mathematical modeling of thermal modes of channel- free heating network laid in the areas of influence of engineering structures, as well as numerical analysis of the heat loss of the objects submitted. The regularities of heat transfer in the system and the factors that influence the intensification of heat losses are revealed. Revealed that thermal losses heating pipes laid in the channel- free zones of influence engineering structures decreases in the range from 1.53 to 10.79%, depending on the temperature inside the engineering structures and geometric characteristics of the system. It is shown that the standard method of calculation of heat loss channel- free heating pipes gives overestimated values of heat loss.
