...Ellann Cohen; Leon Glicksman For semitransparent materials like aerogels, the energy from the hot-wire is transferred by a combination of conductive and radiative heat transfer. The radiative component might not be taken into account properly by means of a short transient test using a fine...

...: Zhixiong Guo. 04 04 2013 07 10 2013 When the transient hot-wire method is used to measure the thermal conductivity of very low thermal conductivity silica aerogel (in the range of 10 mW/m·K at 1 atm) end effects due to the finite wire size and radiation corrections must be considered...

...Gaosheng Wei; Yusong Liu; Xiaoze Du; Xinxin Zhang This paper presents a theoretical and experimental study on gaseous conductivity of silica aerogel and composite insulation materials. First, the insulation material samples (including silica aerogel, xonotlite-type calcium silicate, xonotlite...

...Erik R. Bardy; Joseph C. Mollendorf; David R. Pendergast Aerogel is among the best solid thermal insulators. Aerogel is a silica gel formed by supercritical extraction which results in a porous open cell solid insulation with a thermal conductivity as low as 0.013 W ∕ m K . Aerogels have a wide...
