Uncertainty Updating in the Description of Coupled Heat and Moisture Transport in Heterogeneous Materials

, 2011
To assess the durability of structures, heat and moisture transport need to be analyzed. To provide a reliable estimation of heat and moisture distribution in a certain structure, one needs to include all available information about the loading ...

Model for Ground-Coupled Heat and Moisture Transfer from Buildings [PDF]

, 2003
An important factor in soil heat transfer that is often over looked is the effect of moisture, which can vary the effective thermal conductivity by a factor of ten. The objective of this research was to investigate the ground-coupled heat and moisture transfer from buildings, and to develop results and tools to improve energy simulation of ground ...

Comparison of Algorithms and Parameterisations for Infiltration into Organic-Covered Permafrost Soils [PDF]

, 2010
Infiltration into frozen and unfrozen soils is critical in hydrology, controlling active layer soil water dynamics and influencing runoff. Few Land Surface Models (LSMs) and Hydrological Models (HMs) have been developed, adapted or tested for frozen ...
