This article describes an attempt to modify the transient line source probe to be useful in making in-situ measurements in the field. The field of construction, as well as many others would benefit if a new thermal probe could be applied to uncontrolled environments. Three case study buildings have been considered to ascertain the validity and reliability of this new technique in ...
Asphalt concrete must often endure a range of different weather conditions, and its thermal conductivity is affected by these changes. Using the Finite Element Method (FEM), this paper develops a two-dimensional numerical model used to study and predict environmental effects and validates it through experimental results from the transient plane source method. It was also shown that an increase in the ratio of the TPS sensor size to the maximum ...
This article studied a new asphalt pavement patch repair method that used dynamic infrared pre-heating. The thermophysical properties of the asphalt mixture were measured because they affect heat transfer and storage inside the pavement initiated by the absorbed radiation energy of radiative heat application on the surface of the pavement. One of these thermophysical properties, thermal conductivity, was measuring using the transient line source (TLS) method. From the TLS method, ...
This study investigated the relationship between hygrothermal properties and bulk density of compressed earthen bricks. Thermal conductivity of compressed earthen samples was measured using a thermal apparatus with transient plane source method. Compressed earthen material with lower bulk density was found to have a lower thermal conductivity than higher bulk density materials since low bulk density samples have more pores filled with air....
