Abstract Jet fires may lead to severe consequences in industrial facilities due to the probability of flame impingement on the plant equipment, and the high radiative fluxes emitted by the flames. In this context, this paper examines the flame-geometry descriptors and the surface emissive powers of different type of jet releases, horizontal and vertical, based on experimental data. In addition, FDS simulations of some of the jets reported are performed under different turbulence approaches and mesh resolutions to figure out its predictive capabilities. Recommendations on the most suitable modelling options are delivered by quantitatively comparing the simulation results with the experimental measurements. Given the promising results obtained in FDS, further simulations may be envisaged to figure out numerical correlations describing the main hazardous effects of turbulent diffusion fires.
