Participants are welcomed at CERN and an introdcution to CERN and safety at CERN is given.
The status of a newly developed CFD framework with grid adaptive FEM will be presented, which includes the verification of its flow solver as well as scaling on the JURECA supercomputer.
After a short introduction of the project’s motivation, the applied methods and tools for real-time smoke simulation are introduced.
Then, acceleration results for 2D and 3D test cases are shown and next steps towards complex geometries are touched on briefly.
Finding an appropriate method to use combustion efficiencies in an FDS-Model.
Investigate the influence of different combustion efficiencies on the temperature rise inside a building component.
A Comparison of different optimization algorithms for material parameter estimation is presented. The presentation covers the overall workflow in a parallel computing environment, the performance and accuracy of the algorithms and their special characteristics.
An overview on simulating the cone calorimeter test in FDS is given. Based on data from the CHRISTIFIRE project, an evolutionary algorithm is used to create input parameter sets to be used in large scale fire simulation, later on.
Simulation of organic peroxide fireballs with ANSYS CFX and comparison to experimental data.
Investigation on the baseline flow field in an underground metro station utilising simulation software ANSYS CFX and FDS.
Ambient and fire tests on RC slabs with Glass-FRP bars and conceptual approach to fire safety checks for bending moment resistance of FRP-RC members.
Study of the temperature distribution in space and time beneath a tunnel ceiling subject to a transient fire. Including a description of the structural behaviour of tunnels under fire and the possible failure modes that could be used to estimate the probability of failure of the tunnel.
Structural analysis of concrete at high temperature and fire-structure interaction.
The thermo-mechanical computer modelling for the fire safety of concrete tunnels.
Presentation of a meta (or surrogate) model that interpolates the fatalities, determined in few discrete scenarios by complex fire and evacuation models, to any arbitrary scenario. An advanced Latin-Hypercube design is utilised and its model uncertainty will be described.
