PHAST now includes advanced 3D fire modelling capabilities through Computational Fluid Dynamics (CFD) modules. These modules enable detailed simulation of jet fires, offering deeper insight into fire behaviour -particularly how it interacts with nearby equipment and differing fire characteristics for different fuels.
A particular example is hydrogen. Hydrogen is a buoyant gas that burns with a luminous flame, but with a lower heat flux to its surroundings than with other hydrocarbons (e.g. liquid petroleum gas). The CFD module considers hydrogen’s buoyancy when determining the shape of the jet fire, improving accuracy when determining flame impingement and heat flux to nearby equipment.
At R4Risk, we apply tools such as PHAST’s advanced CFD modules to deliver more accurate consequence modelling, helping our clients better understand and manage fire and explosion risks. Get in touch with our team to discuss how these insights can strengthen your risk management approach.
