Numerical Investigation of a Mechanical Device Subjected to a Deflagration-to-detonation Transition


In this work we evaluate the consequences of the combustion of a stoichiometric mixture of hydrogen-air on a mechanical device which can be considered as a long tube. In order to choose the most dangerous combustion regime for the mechanical device, we devote a particular attention to the investigation of the 1D deflagration-to-detonation transition. Then, once established the most dangerous combustion regime, we compute the reacting  flow and the stress and strain in the mechanical device. Analyses are performed using both semi-analytical solutions and Europlexus, a computer program for the simulation of  fluid-structure systems under transient dynamic loading.
