In this study, the insulating properties of building materials made out of recycled plant particles were tested with both the laser flash method and the Transient Plane Source (TPS) method. The tests were conducted with aggregates of sunflower pith with particle sizes 1, 1.5, and 2.5 mm, to see how the thermal conductivity behaves with increasing air volume fraction between grains. The TPS method produced values with an increasing trend for thermal conductivity ...
This study was conducted to determine if highly expanded open cell polycarbonate foams (PC) could be used as thermal insulation among other characteristics of the foam. This was accomplished through testing the PC foam with the Transient Plane Source (TPS) method. Multiple relative densities of foam were tested, and it was found that the higher the relative density the higher the thermal conductivity, and vice versa. The lower the relative ...
The thermal properties of oil palm shell (OPS) are investigated to determine if it could be used as a lightweight aggregate for a concrete mixture. The thermal conductivity, diffusivity, and specific heat were all tested through a transient plane source (TPS) method. The thermal conductivity and diffusivity both increased as the volume fraction of OPS increased. This is because OPS is very porous which gives it an inherently low thermal ...
Silicone materials have high electrical and thermal insulation properties that are useful for engineering applications. In this study, vapour grown carbon nanofibers (VGCNF) were produced by two different methods and were added to silicone rubber to improve conductivity. A thermal constant analyser measured the thermal conductivities of the silicone and its composites using the transient plane source (TPS) method. Results showed that thermal conductivities of the roll-mill produced VGCNF/silicone ...
Aerogels are nano-porous materials with impressive thermal insulation properties. This study uses a new theoretical model to predict the effective thermal conductivity of aerogels based on gas and solid conduction, as well as thermal radiation. A thermal constant analyzer measured the influence of gas pressure, atmosphere, and temperature on the thermal conductivity of nano-porous materials using the transient plane source (TPS) method. Results showed that the experimental thermal conductivity values ...
