The authors investigated the thermal conductivity and thermal diffusivity of two composite materials, marble and magnesium oxychloride cement. The transient plane source (TPS) technique was the method used to determine the thermal properties of the aforementioned composites. The thermal properties were studied in the temperature range from 30 to 150°C....
In this study, the researchers investigated the thermal conductivity, thermal diffusivity and specific heat of four types of wood: beech, birch, spruce and Douglas fir. The main factor influencing the thermal properties of the wood was the moisture content of each sample, which was manipulated by the researchers. Samples of each type of wood were taken and placed in a hot and wet air flow device for varying times in ...
Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of concrete and wood samples were measured at elevated temperatures. The measured values are compared to established literature values and show good agreement....
Thermal conductivity and thermal diffusivity were simultaneously measured using the transient plane source (TPS) technique. These values were measured during heating from 303 to 323 K and cooling from 323 to 303 K. It was determined that both thermal conductivity and diffusivity were at their maximum at 313 K, which is in the range of the glass transition temperature....
The author compares some currently existing method of measuring thermal conductivity and elaborates on a couple of newer methods. The pre-existing methods include hot wire and laser flash diffusivity, and the newly introduced methods are the modified how wire (MHW) and transient plane source (TPS) techniques. The necessary conditions (samples sizes, sample composition, test times, etc) are explained for the two newly introduced techniques. Experimental runs are carried out using ...
