Mathematical model for nonstationary regime of gaseous hydrogen outflow from vertical pipelines to atmosphere

Numerical simulation on the diffusion of hydrogen due to high pressured storage tanks failure

“…Since the experiment is not easy to carry out for high costs and dangerousness, numerical simulation can be an alternative (Dandrieux, Dimbour, & Dusserre, 2006). In fact, different studies which concentrate on the modeling of gas diffusion have been carried out for several decades such as the Gaussian plume and puff model, the Britter and McQuaid model, the Sutton model and FEM3 (3-D Finite Element) model (Mohan, Panwar, & Singh, 1993;Tanaka et al, 2007;Wilkening, & Baraldi, 2007;Khristenko, Tomilin, & Ryazhskih, 1999). However, these models are not perfect for solving hydrogen diffusion problems.…”
