Some Questions Related to CFD Modeling of Pressurized Tank Burst in Road Tunnels - Ineris - Institut national de l'environnement industriel et des risques

The current paper focuses on high-pressure reservoirs and the consequences of their potential burst, related to scenarios of thermal or mechanical aggressions, in tunnels. CFD modeling can be used to account for the effects of such scenarios. An intrinsic advantage of such an approach consists in integrating the specific geometrical effects (tunnel walls, presence of vehicles) on the pressure wave propagation. To meet such an objective, experimental data are required to offer an opportunity for validation. Data from the literature and new ones from INERIS are detailed in this paper, with their strengths and weaknesses to identify relevant test cases for CFD.....
