The CFD solid combustion modeling is an issue that is still under development due to the complexity of the process, which requires various sub-models for the thermochemical conversion of the biomass and enough computational resources for the simulation (Dernbecher et al., 2019).Fig. 1 presents the main submodels used in the simulation of solid biomass.

everything youll ever need
Im looking to implement a combustion model (flamelet generated manifold) into OpenFOAM. My question is whether anyone could point me in the right direction as to where I can link a subroutine to an existing solver or where I can add an extra transport equation. Any help is greatly appreciated, Pieter.
