FLACS-DustEx (former DESC) is a CFD code for simulating the course of industrial dust explosions in complex geometries.
The first version of FLACS-DustEx was developed in a project sponsored by the European Commission. Apart from Gexcon, there were 10 main participants in the FLACS-DustEx project: HSL, TNO, Inburex, Fraunhofer-ICT, FSA, Øresund Safety Advisors, Warsaw University of Technology, Delft University of Technology, Hahn & Co and Lyckeby Culinar. Contributions were also received from Fike, INERIS, and University of Bergen. The project involved extensive experimental work, measurements in real process plants, modelling and validation. A review of the FLACS-DustEx project has been published in The Journal of Loss Prevention in the Process Industries (see below).
- Experimental input from standardised tests in the 20-litre sphere
- Extensive options for output of results, including 2D and 3D-plots
- Transient pneumatic dispersion of dust from pressurized reservoirs
- Dispersion of dust layers by turbulent flow or blast waves
- Strong ignition sources (e.g. chemical igniters)
- Fast acting valves triggered by sensor points
- Vent panels triggered by internal pressure
- Modelling of vent and fast acting valves to mitigate the effects of explosions
- Realistic representation of industrial plants
- Most kinds of explosive organic dust used in industry (KSt> 100 bas m/s)
- Effect of varying of the ignition point
- Prediction of external blast waves
- Dust lifting by flow or shock waves
- Preasure piling in interconnected vessel systems
- Identifying worst-case explosion scenarios
- Improved models for particle-laden flow and heterogeneous combustion
- Improved methods for geometry building and grid generation
- Reduced grid-dependence on simulation results
- Explosion suppression system triggered by sensor point
