Resumen

Jet fires occurring in industrial facilities can lead to the domino effect. Therefore, the results of a particular study due to the high momentum flame in a particular di- rection or directions. The estimation of the size, shape, thermal radiation, and other semi-empirical correlations of the flames can contribute to ward off accidents that can imply environmental, financial, equipment, and personal losses. Computational Fluid Dynamics (CFD) technique is presented as a tool to help chemical industries predict and assess fire hazards. This paper presents a comparison between experimental and predicted data of subsonic propane jet fires at different correlations - length, area, and equivalent diameter ? using two different flame modelling software’s. Fire Dynamics Simulator (FDS) is used as an open-source and COMSOL Multiphysics v5.6 as a commercial software. The jet fires presented are compared in flame length (Lf), flame area (Af), and equivalent diameter (Deq) come to an agreement between predictions and measurements. Results show that jet fires of 12.75 and 20 mm and mass flows of 0.007, 0.016 and 0.020 kg/s reach a good agreement with the experimental data between FDS and COMSOL Multiphysics v5.6.

Keywords: Jet fire, Computational Fluid Dynamics Simulations, Propane, FDS, COMSOL Multiphysics v5.6.
