Zusammenfassung:Application of a three-dimensional mathematical model for the pyrolysis of wet wood coupled with the gas phase combustion to the analysis of a wood sample ignited in a cone calorimeter is described. Time-dependent chemical and physical processes of wet wood model described in Part I is employed with transient gas phase flow described by Navier–Stokes equations. Predicted ignition times compared well against experimental data for cone irradiation fluxes of 20–70 kW m −2 with initial moisture contents of 0%, 5% and 10%. This study further demonstrates the feasibility of application of the developed wet wood model in fire-engineering.
