The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer.
This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, anisotropic wood sphere. A reaction scheme consisting of five pseudo species, and five reactions, is used.
After that, parameter estimation is used to optimize the model using experimental data. The parameters to be estimated are one Arrhenius constant, two reaction heats, and one external heat transfer coefficient.
