High-performance thermal insulations (HPI) have outstanding thermal properties to minimize heat transfer for a specific application. The term "high performance" is a relative rating: whether an insulating property, i.e. the thermal conductivity or th

Stationary gas turbines are still an important part of today’s power supply. With increasing temperature of the hot combustion gas inside a gas turbine, the efficiency factor of the turbine increases. For this reason, it is intended to operate turb

It has been shown that structural properties of open porous solids, such as the mean pore size, can be derived from gas pressure-dependent thermal conductivity data. However, a reliable prediction of the total thermal conductivity of a porous sample

Although in the case of fluids there are several reference correlations of low uncertainty for thermal conductivity, for solids there are very few and in a restricted temperature range. The available experimental data for the thermal conductivity of

Nanoporous aerogels are excellent thermal insulation materials with thermal conductivities down to about 0.012 W m−1 K−1 at ambient conditions. So far, it was assumed that the total thermal conductivity of aerogels can be described by a simple su
