Numerical Simulating the Ground Coefficient of Thermal Conductivity in Severe Cold Region

Abstract:

The ground coefficient of thermal conductivity is one of the most important parameters of simulating the ground temperature field. The ground coefficient of thermal conductivity of the severe cold region is investigated in this article. Firstly, calculating the ground thermal conductivity with considering the moisture content and porosity; then measuring the thermal conductivity of the 1.5 Meter depth; finally, simulating the unsteady heat transfer model of the shallow buried pipe and the ground with the Matlab software; it founded that the calculation data and the actual data differ only 0.31,but the corresponding ground temperature field vary widely. Thus, it can be concluded that the more precise temperature field of the ground can be simulated with the actual data of ground coefficient of thermal conductivity.
