    Abstract

    Determination of the material parameters is one of the key challenges of numerical fire simulation attempting to predict, rather than prescribe the heat release rate. In this work, we use common fire simulation software and genetic algorithms to estimate the kinetic and thermal reaction parameters for PVC, black PMMA and a power cable. Parameters are estimated by modelling thermogravimetric and cone calorimeter experiments and minimizing the error between the experimental and numerical results.
