Pyrolysis of Wood
Application ID: 118991
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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® et
- soit le Module Battery Design, Module CFD, Module Chemical Reaction Engineering, ou Module Fuel Cell & Electrolyzer
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products.
