In this paper, a local equivalence ratio based toxicity model has been extended to include the calculation of hydrogen cyanide (HCN) by applying a generalised relationship between the normalised yields of carbon monoxide (CO) and HCN. Two full-scale nylon fires have been simulated.
The concentrations of toxic gases are calculated with the extended toxicity model while the release of heat due to combustion is modelled by the eddy dissipation combustion model. The predicted concentrations of CO2 are in good agreement with the measured data and the predicted concentrations of CO and HCN essentially follow the measured trends.
