The CVE (Chambre View Explosion) is an experimental facility owned by the DIMNP at the University of Pisa “Scalbatraio” laboratory to study the confined vented explosion phenomena in real environments. The CVE is a cubic apparatus of 25 m3, equipped with two glass walls that enable to video record the explosion and the flame expansion, and the relevant path. The experimental campaign and the results here presented were focused on the investigation of the turbulence induced by obstacles on the vented deflagration for homogeneous conditions of concentration. For this purpose two sets of obstacles constituted by plates were designed and put inside the apparatus. Besides the experimental activities, also a modelling work has been carried out with the CFD code FLACS V8.1 (FLame ACceleration Simulator) in order to predict and reproduce the turbulent confined hydrogen vented explosion. A comparison between the experimental video recorded data and the same data reproduced through the CFD simulations is presented.
