Computational Fluid Dynamics (CFD) is a powerful, rapidly evolving tool used for the prediction and analysis of fluid flows in very complex geometries.

Abstract

Computational Fluid Dynamics (CFD) is a powerful, rapidly evolving tool used for the prediction and analysis of fluid flows in very complex geometries. CFD is a predictive tool which can be applied at the design stage as well as in assessing a finished structure. It can potentially be used to evaluate the effects of changes in structural design and ventilation, and to assess performance of safety measures over a range of fires; differing size, duration and locations. CFD tools are able to provide a time-dependent three-dimensional approximate solution (temperatures, velocities, concentrations) to the highly coupled differential equations that govern fluid flows. Despite some limitations of this technique (it requires a knowledgeable approach to produce reliable results, complexity, uncertainties in some physical models, such as turbulence), the potential usefulness of CFD is substantial, hence its growing use in Fire Safety Engineering. In the paper, two CFD applications to simulate fires in large enclosed spaces are also presented: a shed for goods storage and an underground parking. In the first case, a fire from wood pallets is studied in transient conditions; in the second application, a preliminary steady state simulation of a car fire is analyzed to provide information on smoke movement.
