This paper presents a CFD analysis of the wind velocity simulated in a portion of the campus of the University of Rome “La Sapienza” (Italy). One of the final goals of this study is the evaluation of the pressure field on the surfaces of the buildings in order to quantify outdoor-indoor exchanges of air mass within a street canyon adjacent to the building of interest. Numerical results concerning the wind field have been compared with in situ data collected in the framework of the VIEPI (Integrated Evaluation of Indoor Particulate Exposure) project.

This paper describes 2-D numerical simulations aiming to reproduce the pressure impulse named confined-crest impact (Castellino et al., 2018), which occurs when a recurved parapet wall and non-breaking wave conditions are interacting. The simulations are carried out by using the IH2VOF and IHFOAM, the latter developed as OpenFOAM additional library. The results show a large increase of the pressures and forces value when the recurved part of the vertical parapet results completely occluded by the non-breaking wave crest.
