Abstract

Computational Fluid Dynamics (CFD) is a simulation tool that uses computers with high processing capacity and applies mathematical models for the simulation of fluid flow patterns, making it possible to predict velocity, temperature and pressure profiles, among other parameters. CFD tools have been increasingly used for the analysis of the consequences of events involving the release of flammable substances, among which are the events of release of flammable gases with subsequent formation of jet fires. However, even though it presented promising results, some studies point to possible distortions found in the results due to the large number of input variables and associated uncertainties, which justifies the research project presented here. This research project is associated to an ongoing FAPESP Project - Regular Aid modality that provides for field tests involving the formation of fire jets, whose data and part of the resources can be used for the research project proposed here. It is expected that this research will be able to compare field tests result with simulations results of scenarios involving jets fires.
