Abstract

This paper describes the R&D work performed within the scope of joint project activities concerning the numerical simulation of reacting flow in complex geometries. The aim is the refinement of numerical methods used in computational fluid dynamics (CFD) by introducing high-performance computations (HPC) to analyse explosion processes in technical systems in more detail. Application examples concern conventional and nuclear energy systems, especially the safety aspects of future hydrogen technology. The project work is mainly focused on the modelling of the accident-related behaviour of hydrogen in safety enclosures regarding the distribution and combustion of burnable gas mixtures, ranging from slow to fast or even rapid flames. For fire and explosion protection, special models and criteria are being developed for the assessment of adequate safety measures to control deflagration-to-detonation transition (DDT) processes. Therefore, the physical mixing concept with dilution and inertization media is studied and recommended.
