Spectrometric Radiation Measurements of Nanoporous Insulation Materials

Abstract:

For the measurement of radiation heat transfer in the low-density nanoporous insulation material at extreme temperature environment, this paper describes in detail on how the experimental optical system is established, and the way and method of measurements are presented .A Silica Aerogel nanoporous insulation plate specimen is experimented and its result is compared with the analytical result, their discrepancies are analyzed. This work is intended to give reference to the development of new types of thermal protection system (TPS) with low density microporous material insulations.
