Abstract
This paper presents a simplified wood combustion model that was developed using a cone calorimeter experiment. Then, the model was validated using another cone calorimeter experiment, an intermediate scale experiment (a wood crib) and a set of large scale experiments. The numerical model successfully reproduced the main characteristics of the cone calorimeter HRR curve; two distinct peaked separated by a semi flat HRR. In case of the intermediate scale test (the wood crib), the numerical model also successfully predicted the main characteristics of the experimental curve: a peak HRR value followed by a semi flat HRR followed by a gradual decay. The large scale experiments were compartment fire tests. Compartment fire validation cases were conducted by comparing numerical results with correlations derived from previous fire experiments. Numerical results were comparable to experimental results in terms of general trend of the HRR curve, duration of the fully developed HRR and the compartment fire temperature.
