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.

由于火焰撞击到工厂设备上的可能性以及火焰发出的高辐射通量，喷射火可能会对工业设施造成严重后果。在这种情况下，本文根据实验数据研究了火焰几何形状描述子以及水平和垂直射流释放类型的表面发射功率。此外，在不同的湍流方法和网格分辨率下，对某些报告的喷气机进行了FDS仿真，以求出其预测能力。通过将仿真结果与实验测量结果进行定量比较，提出了最合适的建模选项的建议。鉴于FDS取得了令人鼓舞的结果，
