Jet fires are a significant hazard for the Oil & Gas industry and can cause both injuries to personnel and failure of equipment and structures. Current jet fire consequence analyses rely almost exclusively on empirical models that use a simplified flame geometry and fixed emissive power to determine the thermal radiation load on a target. The available empirical models provide acceptable radiation load estimates for hypothetical scenarios that are comparable to those used during model development. Computational Fluid Dynamics (CFD) represents an alternative solution for evaluating jet fire geometric features and radiation loads. CFD has been used historically in a wide variety of applications, including but not limited to the aeronautics and automotive industry, the biomedical industry, and in a wide range of industrial applications involving heat transfer and fluid mechanics. With recent advancements in computer power, CFD has become a mature tool that can be used reliably for evaluating the impact of fires. During the facility design process, CFD offers flexibility in evaluating the effect of design changes and provides information to assist in making data-driven design decisions.
This paper describes the current state-of-the-art for jet-fire consequence analysis as well as review publicly available experimental data. A few representative test cases are used to compare empirical models and CFD results with published experimental data.
