Abstract

The flow of smoke under beamed ceilings is simulated using a field model. This work was performed in order to confirm that fire detector response can be evaluated using computational data obtained from numerical simulations as well as laboratory data obtained from experiments. The field model is verified for this application by showing that its temperature predictions match experimental results obtained by Heskestad and Delichatsios. Line plots are presented which show that the numerical and experimental temperature measurements are in good agreement. Contour plots are also presented that show the temperature distribution in the channels formed by the ceiling beams. Finally some preliminary results involving the effect of beam depth on smoke flow are presented.
