This paper used the TPS to measure the thermal conductivity of several different spray applied fire resistive materials between a temperature of 20-1000°C. Mass loss and thermal strain were also investigated. These properties are crucial components of the material, and decide how effectively it will perform in the face of a fire. Temperature was found to have a significant impact on the thermal conductivity, mass loss and thermal strain. ...
The thermal conductivities of gas hydrates are well documented, but the thermal conductivities of structure H (sH) methane-methylcyclohexane (MCH) hydrate and type A tetrabutylammonium bromide (TBAB) semi clathrate hydrate have no experimental data. The purpose of this study was to determine the thermal conductivities of sH MCH hydrate and TBAB semi clathrate hydrate. The thermal conductivity was measured using a single sided transient plane source (TPS) method. Most gas hydrates ...
This study developed a model that used a transient plane source (TPS) sensor to measure the specific heat capacity of anisotropic materials. The underside of a sample holder with a diameter of 20 mm, and a height of 5 mm was attached to a Kapton TPS sensor. During measurements, the sample holder was hung inside a steel tube at atmospheric pressure. Results showed that the model underestimated the heat capacity, which suggests ...
This paper presents the idea of flavonoid foams that are manufactured from natural resources rather than formaldehyde-containing tannin-based foams. A TPS instrument measured the thermal conductivity of the foams using the transient plane source (TPS) technique. Results show that the flavonoid foams are a better choice than tannin-based foams because they have a lower thermal conductivity which makes them more insulative and fire resistant, and they do not release toxic ...
The Transient Plane Source (TPS) Technique measures the thermal conductivity, thermal diffusivity, and specific heat of solids and liquids. An electrically conducting double spiral nickel sensor pulses a current through a sample which increases its temperature, while simultaneously recording the length of time it took for the sample to heat up. This study, researchers tested the thermal properties of various materials and determined that anisotropy must be considered when these ...
