Radiative Conductivity Estimation Using Direct Approach For Fibrous Materials

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

A one dimensional, coupled radiation-conduction code is used to estimate the temperature dependent solid thermal conductivity of a fibrous ceramic insulation material. The proposed method solves for the unknown thermal conductivity as well as the surface heat fluxes using internal temperature solutions, and does not presume any prior functional information for the thermal conductivity. The radiative heat transfer is being accounted for using the P1 approximation and was verified against analytical solutions. Multiple test-cases were included to validate the use of the proposed method.
