LUNCHTIME WEBINAR - 30th SEPTEMBER 2020
We are pleased to inform you that our next FABIG Lunchtime Webinar will cover 'A look back on developments in fire modelling' and will be given by Bjørn Erling Vembe, DNV GL on 30th September 2020 from 13.00 BST.
For additional information and registration, please go to the Events section of the website.
Mathematical modelling of fire stretches back to the 50s and 60s. The first models were based on dimensional analyses and correlations derived from experiments. The most famous are the Thomas correlation from the early 60s which is used for calculating flame heights from pool fires and later the Heskestad's plume correlation which gives the flow conditions in fire plumes. Later in the 70s when computers became available, compartment fire models and structural heat conduction models became tools available for engineers. The first compartment fires were typically calculated by one or two zone models where fire, mass and heat transfer between the zones were resolved by simple correlations. As data power increased, Computational Fluid Dynamics (CFD) codes have enabled us to directly calculate the flow fields and made it possible to analyse far more general and complex geometries. Simple correlations are still useful in relevant contexts. When simple correlations come short, it is quite common nowadays to use CFD codes to simulate fires. Today’s CFD tools for fire and explosions contain several sub-models for combustion, toxicity, soot and radiation. Furthermore, fire loads are integrated directly with structural response. CFD tools give the ability to evaluate fire risks, complete structural response including also the effect of passive fire protection (PFP), smoke spread and influence on human response and evacuation. The effect of active fire protection measures such as deluge, water monitors, curtains, etc. on both fires and structures can also be accounted for in CFD simulations.
FABIG WEBINAR SERIES
We will be organising lunchtime webinars every two weeks whilst working life remains disrupted by measures to combat the COVID-19 epidemic. Such measures either prohibit or make inadvisable large meetings such as our Technical Meetings.
We are now looking for presentations covering the topic 'Robust Principles for Safe Design against Fires & Explosions based on Experience' for our next Webinar Series starting in November and as such, please do not hesitate to contact us at firstname.lastname@example.org if you or one of your colleagues would like to give a relevant presentation.
Take care and stay safe,
