Comparison of Experimental and Simulations Results of a Large-Scale
Propane Jet Fire using CFD and DNV-Phast Software
Abstract
In the present study, vertical propane jet fires are simulated using
computational fluid dynamics (CFD) with Shear Stress Transport (SST),
Eddy Dissipation Concept (EDC) and Monte Carlo. These models are used
for turbulence, combustion and radiation, respectively, and the results
are compared with the DNV-Phast 7.2 software. The predicted radiations
are validated at three horizontal distance points. The results show that
the average radiation error predicted by the DNV-Phast 7.2 software and
the CFD method with experiments data were 98% and 10.5%, respectively.
The simulation results also show that it is not possible to accurately
predict the amount of radiation during a propane jet flame by using the
DNV-Phast 7.2 software; whereas the CFD simulations determine the amount
of radiation at all locations
