A6. Introduction

Conclusions of the modelling programme and recommendations for the IPG.

Introduction

This appendix summarises the final chapter of Deliverable 4.3 Releases, Fires, and Explosions, Modelling Report [1], produced within Work Package (WP) 4 of the FP6 specific targeted research HYPER.

WP4, entitled ‘Risk Evaluation – Modelling’ was primarily concerned with the modelling and simulation activities performed within HYPER and was closely linked to the experimental programme in WP5 ‘Risk Evaluation – Experimental’.

The HYPER project was organised into seven work packages. Initially, existing codes and standards relevant to small stationary hydrogen and fuel cell systems were examined and gaps in the literature were identified within WP1 [2]. These findings were subsequently used to shape the experimental and modelling programmes and define a number of key potential accident scenarios relevant to small stationary hydrogen and fuel cell systems. These accident scenarios were investigated in both the modelling and experimental programmes.

A key aim of both WP4 and WP5 was to generate new scientific data and knowledge in the field of hydrogen safety, and, where possible, to use this data as a basis to support the recommendations in the installation permitting guidelines. Further details on specific aims of WP4 are given on the following page.

This appendix summarises the findings of the modelling work performed within HYPER. While some experimental findings are given here, this appendix focuses on WP4, and the reader is referred to Appendix 5 and [1, 3, 4, 5] for more details on the work performed on the experimental and modelling reports delivered within HYPER A
