Objective
A transition from Deflagration to Detonation (DDT) in H2-air-steam systems relevant for severe accident scenarios can produce loads threatening the integrity of nuclear reactor containments. The proposed joint project aims at revealing the physical mechanisms of DDT processesthrough experimental as well as theoretical/numerical investigations and at deriving reliable criteria for the prediction of DDT events. These criteria will be incorporated in the numerical codes for large scale explosion simulations developed recently by the participants.
Two distinct routes towards the establishment of a detonation will be explored.
MODE A - DDT involves local explosions and the establishment of detonation in the unburnt gas flow that is driven by a high-speed deflagration. MODE B - DDT is defined by local quenching and re-ignition sequences within the turbulent flame brush. Specific experiments and theoretical/numerical analyses will be performed in order to develop overall predictive capabilities including both transition modes.
This will result in appropriate predictive tools, which will allow to explore adequate coutermeasures to DDT events. The results gained are useful for the refinement and optimization of mitigation measures of new nuclear reactor concepts.
