However, thermal conductivity of HGMs at vacuum in room temperature has rarely been investigated. In this work, thermal conductivity of six types of HGMs (T17 (0.17g/cm), T20 (0.20g/cm), T22 (0.22g/cm), T25 (0.25g/cm), T32 (0.32g/cm) and T40 (0.40g/cm)) at vacuum in room...
The high thermal performance of VIPs is mostly achieved by reducing the gas thermal conductivity (λg) via reduction in pore pressure of core material; and the most effective reduction is achieved at total vacuum, when λg could approach zero [6], [7]. Maintaining the vacuum state in VIPs...

An attempt to measure the thermal conductivity of liquids, gases, and vapors with a high degree of accuracy over wide ranges of temperature (−180 to 500°C) and pressure (vacuum to 500 atm) A new thermal conductivity cell is described using a vertical cylinder with hemispherical ends ...
2.1.3 Thermal conductivity of high-temperature PCMs Thermal conductivity is a measure of how well PCMs conduct heat. High-temperature PCMs with high thermal conductivity can accelerate the rate at which energy acts on the entire material, improving the thermal energy usage efficiency while lowering ...
The first measurements of the thermal conductivity of powders [1] showed that powders can be an interesting alternative to vacuum systems for achieving good thermal insulation. Currently powders of different materials (ceramics or polymers) are used in packaging or for building insulation. On the oth...
