Abstract: Wind-driven rain studies provide the main input to problems such as: precipitation protection, sealing, drainage accumulation. A Computational Fluid Dynamics (CFD) methodology is developed and used to compute trajectories and local intensity factors for two generic buildings, previously tested in the wind tunnel. The methodology is further on applied in investigating real problems such as the role played by cornice in protecting the upper part of a low-rise building or the wetting and downwash on a sloped face of a high-rise building.
