Understanding the pyrolysis model for medium density fibreboard (MDF) is important for infrastructure fire safety. The purpose of this study was to determine the thermophysical properties of charred and uncharred MDF. The thermal conductivity of these inhomogeneous fibreboards was measured using a Thermal Constants Analyser in conjunction with the transient plane source (TPS) technique. Results showed that the experimental results were in good agreement with literature values, and specifically, the ...
Polypropylene (PP) foams are commercially manufactured in four ways, with each method producing different characteristics. The aim of this paper was to examine the properties of each PP-based foam and compare their thermal behaviors and conductivities. A thermal constant analyzer was used to measure the thermal conductivity of the foam samples with the transient plane source (TPS) technique. Results showed that thermal conductivity varied for each production method, but density ...
The transient plane source (TPS) method, was used for the determination of thermal conductivity and thermal diffusivity of solid materials. Researchers developed a model based on the thermal quadrupoles formalism to represent the temperature variation. This model was able to take in account the thermal contact resistance of the material and the thermal inertia. The TPS method makes it possible to calculate the parameters estimation on all the recorded temperature ...
Phase change materials (PCMs) can be used as heat sinks to manage high temperature fluctuations in electronics. In this paper, a heat sink was generated from a paraffin/expanded graphite composite PCM, and the thermal conductivities of the materials were measured using the transient plane source (TPS) method of the Thermal Analyzer. Results showed that the composite PCM had a significantly higher thermal conductivity than the pure paraffin....
This study looks at U-values and heat transfer for houses built in Libya, of which the majority studied were built in the 1970's when the locally produced building materials didn't consist of any insulating materials. Measurements of thermal conductivity of the various building materials were made. Additionally, the researchers developed a theoretical model that could estimate U-values from measured thermal conductivity values. It was determined that U-values were quite high, ...
