Abstract: | A numerical model has been described to estimate the effective thermal conductivity of moist soils, considering the effective
continuous medium approximation and taking all possible interactions. Numerical solutions of the exact formulations are presented.
Experimental measurements have been carried out for the thermal conductivity of dune sand at different moisture contents employing
the method of unsteady state line source. The predicted and measured values show reasonable agreement. |
