Standard Benchmark Exercise Problems
a framework for validation of codes and models for simulation of problems
relevant to hydrogen safety
of the main priority areas for the further development of the codes
Description of work
Code application simulations will be performed by partners
in order to reproduce experimental data. Existing data will be used to start
this activity. Relevant cases for SBEPs will be selected by review available data.
Comparative assessments of code performance will be given and directions towards
further development will be identified.
The experiments for SBEP will be selected using criteria, which will be based on the relevance to Hydrogen Safety of the phenomena explored in the tests, the availability and feasibility of the data and their possibility to be used for validating mainly CFD codes.
Different codes and models (see Appendix A) will be assessed by the partners involved. These tools will cover the different approaches used in each phenomenon, i.e. integral, CFD (1D to 3D), in-house, commercial both specific and multi-purpose.
Benchmarking exercises should therefore benefit from the complementarities
arising from the variety of codes, models, approaches, user experience and
points of view from industry and research agents. Quality and suitability of
codes, models and user practises will be identified by comparative assessments
of code results, which constitute the essentials of the SBEPs. Directives
towards further development and recommendation for optimal tools and user best
practises for phenomena and approaches will be provided.
