This article looked at the simulation model used to control temperature evolution in the field for Swedish nuclear waste repositories. Heat transport properties of rock are known key factors for the repository layout and were measured using the Transient Plane Source (TPS) method. Compared to all samples tested, results found bedrock dominated by deformed granitoid rocks were characterized by relatively high thermal conductivities. ...
This study highlights the ongoing search for sustainable and thermally suitable phase-change materials (PCMs), for hot weather building climates, such as Iraq. This new PCM must have an extraordinary heat and cold retention ability. Building industries are interested in using paraffin’s in their roofing materials, because of their thermo-physical properties, their profitability to save on electricity and HVAC (heating-ventilating air conditioning) systems, their local abundance, as well as their ...
Insulation is a vital component in the construction industry, notably in this study, glass wool. Maximizing the hydrothermal performance of glass wool is key when dealing with water vapor, humidity and permeability. Although insulation does not generally come in contact with liquids, it is important to consider all outcomes, with likelihood of accidents occurring and the varying levels of workmanship. The transient technique was employed to thermally characterize glass wool ...
The Transient Plane Source was used to measure the thermal conductivity of three commonly used building materials in Libya. Changes in construction practices have resulted in houses being constructed of much thinner materials in comparison to the traditionally thick walls common a few decades ago. Technical data that would make modelling heat flow is these newly constructed buildings is lacking. The indoor environment of these newer buildings often undergoes large ...
This article studied the thermal conductivity of samples of autoclaved aerated concrete with various densities at high temperatures in order to produce data that could be used to assess and predict the performance of buildings during a fire. The mica sensor was employed for high temperature measurements. The values obtained by the authors experimentally were then compared against the reference values provided by national and international standards for high temperature ...
