Gareth Steele, Principal Fire Engineer, London Fire Brigade
·
Is CFD an appropriate design
tool in fire?

Selecting your fire simulation tool when dealing with
uncertainty
Michael Spearpoint, Research Leader, OFR
·
What are some of the characteristics
of the simulation tools that are available to the fire engineer?
·
How does the ability of the
user influence what might an appropriate tool for a given task?
·
Where does uncertainty
exhibit itself in fire engineering design and what does this mean for the
user and their choice of simulation tool?

Afternoon Keynote Presentation
Validation of fire dynamic simulations before or after
seeing the experimental results: A priori vs. A posteriori
Guillermo Rein, Professor of Fire Science, Imperial College London
· We compared 7
independent forecasts and to the measurements of a detailed fire experiment
inside a modern flat
· There was a large
scatter and considerable disparity among predictions and measurements
·
Inherent difficulty of modelling fire dynamics and the
patent difference between predictions made before or after seeing the
experimental results

PRISME3 and fire
modelling in the UK nuclear regulatory framework
Jacob Plummer, Nuclear Safety Inspector, Office for Nuclear Regulation
· An overview of UK’s
regulatory approach to hazard analysis
· The use and
significance of detailed fire modelling in UK nuclear safety cases
· An overview of the
PRISME3 benchmark modelling exercise, its key findings, and its relevance to
the UK nuclear industry
·
Future opportunities and challenges for the PRISME
programme and CFD modelling in UK nuclear safety cases

Multiphysics
Simulations of Fire inside the Cavity of a Façade
Benjamin Khoo, Department of Mechanical Engineering, Imperial College
London
· The growing number
of facade fires worldwide is worrisome, and simulations are an excellent
complement to experiments to help safer design
· Difficulties in
cavity fire simulations are the boundary layers and the multiphysics of flow,
heat and chemistry
· Results show a
non-linear relationship between fire power cavity width
