Numerical experiments and compartment fires
Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. An alternative or complement to these often expensive and resource demanding traditional experiments are numerical experiments. In this paper, numerical experimen...
متن کاملNumerical Simulation of Low-pressure Explosive Combustion in Compartment Fires
Title of dissertation: NUMERICAL SIMULATION OF LOW-PRESSURE EXPLOSIVE COMBUSTION IN COMPARTMENT FIRES Hu Zhixin Doctor of Philosophy, 2008 Dissertation directed by: Professor Arnaud Trouvé Department of Mechanical Engineering A filtered progress variable approach is adopted for large eddy simulations (LES) of turbulent deflagrations. The deflagration model is coupled with a nonpremixed combusti...
متن کاملFires in Tunnels: Experiments and Modelling
The development of fire safety research in road tunnels during the past 20 years is reviewed, with particular reference to the activity of the Flame Research Group at Politecnico di Torino (Italy). Simulations of fire accidents in tunnels are described for both full-scale tests in real tunnels and for laboratory-scale tests. It is shown how simple semiempirical thermo-fluid dynamic models are a...
متن کاملLarge-Eddy Simulation of a Turbulent Lifted Flame in a Vitiated Co-Flow
Large-eddy simulation (LES) of a lifted flame in a vitiated co-flow has been performed using an unsteady flamelet/progress variable (UFPV) model. This model is an extension to the steady flamelet/progress variable approach, and describes the transient autoignition process of the lifted flame through the unsteady flamelet model. The particular advantage of this model is that it eliminates the fl...
متن کاملModelling Aspects of Sprinkler Spray Dynamics in Fires
S prinklers are used extensively in a variety of fire protection applications. These systems are required to perform effectively over a wide range of extremely harsh and complex operating conditions. The sprinkler performance depends on the initiation, formation, dispersion and surface cooling characteristics of the sprays created by these devices. The behaviour of sprinkler sprays is strongly ...
