Simulation of Under-Ventilated Fires

Simulation of Large industrial Outdoor Fires

A methodology for simulating the dynamics of large industrial fires in the outdoor environment is presented. The large eddy simulation techniques developed by the authors and their collaborators are used to simulate a fire on top of a large oil storage tank adjacent to several neighboring tanks. The governing equations are modified to account for the stratification of the ambient atmosphere. A ...

Title of Document : Flame Extinction and Air Vitiation Effects In FDS In Poorly Ventilated Compartment Fires

Title of Document: Flame Extinction and Air Vitiation Effects In FDS In Poorly Ventilated Compartment Fires Zhixin Hu, Master Thesis, 2005 Directed by: Arnaud Trouvé, Associate Professor Department of Fire Protection Abstract: Compartment fires with different ventilation conditions exhibit different dynamical behaviors, ranging from steady fuel-limited fires to unsteady airlimited fires. Numeri...

Parallel Computing of Numerical Simulation in Building Fires

Fire Dynamics Simulator parallel computing program has been compiled based on Message Passing Interface. The fire flow field is divided into several segments and each segment is allocated to the corresponding node to calculate. The calculation shows that computing time has been significantly reduced as the amount of processors increase. The procedure and method that the text has established is ...
