This is an implementation of radiative heat transfer solvers in MFIX for gas-solid reacting flows. MFIX (https://mfix.netl.doe.gov/) is an open-source package for dense gas-solid reacting flows.
Current implementations are based on multi-fluid methods (Eulerian). Solving radiative heat transfer involves a spectral model and an RTE model.
The current release has one spectral model (gray) and one RTE model (P1). The coding structure supports adding other spectral or RTE models easily.
