Simulation of Wood Combustion in PATO Using a Detailed Pyrolysis Model Coupled to fireFoam

The numerical simulation of fire propagation requires capturing the coupling between wood pyrolysis, which leads to the production of various gaseous species, and the combustion of these species in the flame, which produces the energy that sustains the pyrolysis process. Experimental and numerical w...
