Combination of a fire model and a smoke sensor model

A combination between a fire model and a smoke sensor model has been developed. For the realization of the combined fire and smoke sensor model, output parameters of the fire model have to be converted into input parameters of the sensor model. With respect to the simulation of the smoke evaluation during a fire, most fire models give the smoke mass density as a result. For the simulation of a smoke sensor, information about the size distribution of the smoke particles is needed. The developed model gives the opportunity to simulate the response of a smoke sensor whereby the simulation of the fire is included. The goal of the development of this combined model was to provide a tool for the simulation of EN54 test fires. The model has been validated for EN54 test fires, and results of numerical simulations of EN54 test fires with this combined model are presented and discussed.
