CFD simulations of the wind speed conditions in passages between generic parallel building configurations are performed. CFD validation is conducted based on published wind tunnel data. The computational results agree well with the experimental data when an appropriate grid resolution is employed. The required grid resolution across the passage width appears to be a function of the passage width and the building influence scale. A grid resolution guideline is provided. Finally, the simulations and the measurement data are used to identify three different types of passage flow as a function of the dimensionless ratio of passage width to building influence scale.
