Structural response for vented hydrogen deflagrations: coupling CFD and FE tools
This paper was presented at the Seventh International Conference of Hydrogen Safety (ICHS 2017) in Hamburg on 11-13 September 2017. This paper describes a methodology for simulating the structural response of vented enclosures during hydrogen deflagrations. The approach adopted entails full spatial mapping of explosion loads predicted with the computational fluid dynamics (CFD) tool FLACS-Hydrogen to the non-linear finite element (FE) IMPETUS Afea solver. The modelling involves one-way coupling of pressure loads taken from either experiments or CFD simulations to the FE solver. The performance of the combined model system is evaluated for vented hydrogen deflagrations in 20-foot ISO containers. The paper is a deliverable from the project “Improving hydrogen safety for energy applications through pre-normative research on vented deflagrations”, or HySEA (www.hysea.eu), which receives funding from the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) under grant agreement no. 671461. ; The work described in this paper is a deliverable from the project "Improving hydrogen safety for energy applications through pre-normative research on vented deflagrations", or HySEA (www.hysea.eu), which received funding from the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) under grant agreement no. 671461.
