The Transient Plane Source method was used in this research article to measure the thermal conductivity of an Ionanofluid, highly stable graphene (GE)-based nanofluid, at various temperatures. Researchers took special note of the effects of temperature, GE loading, presence of multi-walled carbon nanotubes (MWCNTs), on the thermal conductivity of the nanofluid. Through experimental testing, it was determined that the nanofluid elicited a higher thermal conductivity, as compared to its ...

In this article, researchers aim to improve the thermal management of Li-ion batteries, by introducing graphene fillers to hybrid phase change materials. The thermal management of any battery is dependent on the latent heat stored within the phase change material as it transitions phases. During this time, it is also crucial to reduce the chances of an internal temperature rise. Researchers used a thermal analyzer to determine the thermal conductivity ...

Using the Transient Plane Source technique, various geopolymers, metakaolin-derived sodium (Na), sodium-potassium (NaK) and potassium (K), were tested to determine the effect of varying environmental conditions, such as temperature and humidity, on thermal conductivity. The results concluded that the thermal properties of the geopolymers derived from metakaolin are not greatly affected by the Si/Al ratio in the as-cured state. When the sodium geopolymers were tested at 50% relative humidity, the ...

With the use of multiple thermal instruments, the thermal conductivity (lambda) of fibrous insulations was measured in the plane direction. In this study, a method was put forth the estimate thermal conductivity. This method assumed that the thermal conductivity of the anisotropic material was equivalent to that of an isotropic material with identical bulk density and specific heat. This novel method displays the thermal conductivity of the anisotropic material as √(...

This paper studied in-depth the transient hot plate method, by comparing this method to others in order to develop a short test time in which thermal effusivity and thermal conductivity can be measured simultaneously. To investigate this proposed model, four metal samples were analyzed using various techniques to ensure the accuracy between methods. To encompass a wide thermal conductive range, the thermal conductivities of the four metal samples tested, ranged ...
