Fuites d’hydrogène sous pression enflammées et non enflammées : concentration, mesure de turbulence et effets de surpression

Abstract : Safety studies for production and use of hydrogen reveal the importance of accurate prediction of the overpressure effects generated by delayed explosions of accidental high pressure hydrogen releases. Analysis of previous experimental work demonstrates the lack of measurements of turbulent intensities and lengthscales in the flammable envelope as well as the scarceness of accurate experimental data for explosion overpressures and flame speeds. Industry and INERIS join a collaborative project to study un-ignited and ignited high pressure releases of hydrogen. The purpose of this work is to map hydrogen flammable envelopes in terms of concentration, velocity and turbulence, and to characterize the flame behaviour and the associated overpressure.
