HOMOGENEOUS HYDROGEN DEFLAGRATIONS IN SMALL SCALE ENCLOSURE. EXPERIMENTAL RESULTS

Schiavetti Martino; Pini Tommaso; Carcassi Marco

University of Pisa performed experimental tests in a 1 m3 facility, which shape and dimensions resemble a gas cabinet, for the HySEA project, founded by the Fuel Cells and Hydrogen 2 Joint Undertaking with the aim to conduct pre-normative research on vented deflagrations in real-life enclosures and containers used for hydrogen energy applications, in order to generate experimental data of high quality. The test facility, named Small Scale Enclosure (SSE), had a vent area of 0,42 m2 which location could be varied, namely on the top or in front of the facility, while different types of vent were investigated. Three different ignition location were investigated as well, and the range of Hydrogen concentration ranged between 10 and 18% vol. This paper is aimed to summarize the main characteristics of the experimental campaign as well as to present its results.
