Abstract
An algorithm for predicting smoke or carbon monoxide concentration in the ceiling jet in the presence of a smoke layer is developed. The analysis will be restricted to fires that produce turbulent plumes and can be represented by axisymmetric point sources. The predictions of the algorithm for smoke and carbon monoxide are compared with experiments. Once the smoke or carbon monoxide concentration in the ceiling jet is predicted, the activation times for detectors can be calculated using a model for detector activation.Citation
