3 ACTIVITIES

4 JIP MEASURE Modelling Escalating Accident Scenarios and the Use of Risk-reducing technology for Explosion safety

5 JIP MEASURE Statoil, Total, Engie, ExxonMobil, DNV GL and BP. The experimental campaign is conducted in cooperation with Shell. DNV GL performs the experiments at Spadeadam Fundamental improvements to FLACS Turbulence models Combustion models Parameter optimization Challenging project: Significant changes to model system Extensive validation

6 A.1.1: Literature study turbulence A.1.2: Upgrading Porcalc A.1.3: Implementing limiters A.1.4: Alternative turb. models A.1.5: Verification & validation turbulence model A.3.1 & A.3.2: Verification, Validation & A.2.1: Literature study combustion A.2.2: Flame model A.2.3: Flame folding model A.2.4: Burning velocity correlation A.2.5: Verification & validation combustion model Optimization of combined model system B.1: Planning the experiments B.2: Experimental campaign (DNV GL, Spadeadam test site)

7 LNG Approval of FLACS v10.3 FLACS 9.1 approved by Federal Energy Regulatory Commission (FERC) in 2011 Ongoing approval process for FLACS v10.3 Thorough process Revised procedures and database Laboratory vs. large-scale experiments? Will result in model improvements Necessary to shorten processing time (v10.5!)

8 PhD projects

9 Integrated validation framework

10 3DRM

11 Pros and cons of 3DRM Advantages: Step-wise implementation: 3D risk, Communication with and/or between stakeholders Competence building: CFD vs. engineering models, Limitations: Implementation costs Not an expert system (probably an advantage ) Full implementation requires dedicated end-user

12 Hy3DRM: Hypothetical filling station

13 Example: Jet fire scenario

14 Heat radiation contours: f > 10-6 yr -1

15 10 Lethality frequency jet fire 10-4

16 Application Hydrogen filling station at Karlsruhe Institute of Technology (KIT) Visited during IEA HIA Task 37 meeting in April 2015

21 HySEA HySEA: Improving Hydrogen Safety for Energy Applications through pre-normative research on vented deflagrations ( ) Consortium: Gexcon (Coordinator), University of Warwick, University of Pisa, Fike Europe, Impetus Afea and University of Science and Technology of China (self-funded) Total budget: About 1.5 MEUR Started on 1 September 2015 Website:

22 Work packages

23 First progress meeting Fike Europe, Herentals, 3-5 February 2016 Further information:

24 HySEA Blind-prediction study Open for everyone Explosion pressure and (optional) wall deflection Live demonstration tests and workshop during the first HySEA workshop in Bergen 8-9 September The announcement will be distributed to FLUG

25 The HySEA consortium: The HySEA project receives funding from the Fuel Cells and Hydrogen 2 Joint Undertaking under grant agreement No This Joint Undertaking receives support from the European Union s Horizon 2020 research and innovation programme and United Kingdom, Italy, Belgium and Norway.

26 PROSPECTS

27 JIP DOWSES Development Of Water Spray Explosion Suppression (DOWSES) Continuation of JIP MEASURE Support from DEMO 2000 (25 %) Coordinated by DNV GL Experiments Simulations

28 Multiphase flow modelling Coordinated efforts General framework: Particle-laden flows Droplet-laden flows Various applications: Solid fuel Solid suppressant Liquid fuel Liquid suppressant Disinfection Pollution Etc. Gexcon collaborates with DeconX: on optimizing a disinfection system based on hydrogen peroxide.

29 JIP AIRRE Realistic releases in congested geometries Validation and focus on methodology Coordinated by Gexcon

30 Risk and 3D geometries Risk analysis: Understand the system! Avoid rituals embrace automation! Credit risk-reducing measures! Different focus in design and operation! Initiative toward AVEVA and AKER Aim to establish JIP or similar Starting with 3D geometries

31 Miscellaneous New solver: Flacs 3 (work in progress) Vagesh: Associate Professor in the Fluid Mechanics Group, Department of Applied Mechanics, at IIT Madras Ski Sprint 2016
