“…The CFD code ADREA-HF was used for all simulations in this study. ADREA-HF is a general purpose CFD code which has been extensively validated against flow and dispersion experiments (Venetsanos et al 2010, Efthimiou et al 2017a. It uses a finite volume method on a staggered Cartesian grid.…”

Large Eddy Simulation (LES) of atmospheric flows has become an increasingly popular modelling approach within the last years, as it has the potential to provide deeper insight into unsteady flow phenomena. LES can be improved and validated using specifically designed and well documented wind tunnel datasets. In this work, we evaluate the performance of LES against a wind tunnel experiment in a semi-idealized city ("Michel-Stadt"; CEDVAL-LES database) and use the LES results to study the structure of the turbulent flow at the particular urban area. The first, second and third order statistics are presented, as well as velocity frequency distributions and energy spectra. The results compare well with the experimental values. Information about special features of the flow field is also provided. A particular focus of this work is put on the influence of grid resolution on the results. Five different grids are examined and the required resolution for turbulent flow within the canopy layer is evaluated. This study reveals the strong potential of LES for urban flow simulations. It is shown that LES can assess highly non-Gaussian flow behaviour in street canyons, which has implications for urban ventilation, wind comfort assessment and urban design.

“…For the CFD simulations the ADREA_HF code was used [11]. The model used solves the spaceaveraged Navier-Stokes equations along with the energy equation and the conservation equation of each of the mass fraction of the species that take part in the combustion process.…”

“…In the last few years, there were several studies addressing various aspects of hydrogen safety with different objectives and methodologies that including: risk assessment/analysis on fueling stations [7e11], on distribution System [10], private car [12], and production facility [4]; consequence assessment/ analysis on fueling stations [13,14], and hydrogen applications [15]; QRA (Quantitative Risk Analysis) on fueling stations [16,17], and on generation unit [2]; risk/accident modeling on hydrogen station [18,19]. It can be clearly seen that the most studies are carried out on refueling stations, its transportation and other consumer facilities.…”
