Abstract
The results of the numerical analysis of thermal regimes and heat loss of the two-channel underground heating networks with using the convective-conductive model of heat transfer are presented. The two-dimensional coupled stationary problem of convective-conductive heat transfer in the system «underground two -channel heat pipeline - environment» is solved. The solution of the problem was obtained by the finite element method with using an uneven finite-element grid. The scales of heat loss and the patterns of heat transfer in the zones of underground two-channel heating networks are established. The possibility of analyzing the heat loss of two-channel heating networks with using of the model and the methodology for calculating the heat loss for single-channel heating networks is shown.
