Computational Fluid Dynamics
In some situations, the simplifying assumptions made with practical modeling solutions do not apply. In these cases, detailed analysis is needed. The techniques of Computational Fluid Dynamics (CFD) are required to find solutions to complex problems where other, simpler models are not appropriate. For these situations we turn to CFD.
For studies requiring CFD, Quest uses the open source software package Fire Dynamics Simulator (FDS), developed by the National Institute of Standards and Technology (NIST). FDS is a CFD model which numerically solves a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an emphasis on smoke and heat transport from fires. Quest has used FDS to model various fires, as well as vapor dispersion.
