Description

The study explores the impact of spectral radiative heat flux on material response by developing a coupling scheme between the KATS-MR code and a P1 approximation model for radiation transfer. A band model is created, dividing the spectral domain into small, unequal bands. Verification studies compare the band model’s results with pure conduction and the fully resolved radiative transfer, showing its computational efficiency for simulating material response under spectral radiative heat flux. Simulations using spectral boundary conditions reveal higher internal temperatures and earlier decomposition within the material.

Summary

The study develops a computationally efficient band model to simulate material response under spectral radiative heat flux, showing that this approach leads to higher internal temperatures and earlier decomposition compared to conventional methods.
