- Abstract
- The interaction between a ceiling jet and smoke detector is being investigated with computational fluid dynamics (CFD) modeling in order to better under aerosol entry phenomena. The CFD modeling is performed in two stages. The first stage simulates the bulk transport of smoke from the fire to the detector location. The second stage uses the ceiling jet conditions from the first stage as an inlet boundary condition. The geometry of a smoke detector and the fluid region in its immediate vicinity are modeled in order to examine the nature of the aerosol entry for the given inlet condition and geometry.
