Finally, we relate our findings to several typical applications and compare the analytical predictions with field results. heat transmission thermal insulation moisture content predictive modeling vapor...

... Countless inputs are used in transient hygrothermal analysis, just as countless variables determine the long-term hygrothermal performance of a real-world building envelope assembly. One variable often overlooked, oversimplified, and inaccurately accounted for is the initial moisture content...

While the thickness of the materials is generally unchanged, the conductivity of the material will vary depending on its exposure to moisture. The moisture content of a building material can be impacted by direct exposure...

... procedure for determining the equilibrium moisture content of samples during the experiment. The method (referred to as the balance method) is to simply keep track of all water entering and leaving the system and use these data to estimate the moisture content of the samples. The advantage of this approach...

The objective of this study was to identify the effects of moisture content and pore water pressure on the resilient modulus (M r ) of unsaturated and saturated cohesive soils. Test results conducted on unsaturated cohesive soils at three...
