Spatial distribution of pressure drag acting on rectangular block arrays with various layouts

This study reported a series of wind tunnel experiments on the spatial distribution of the pressure drag acting on the walls of rectangular block arrays, which were arranged in staggered, square, and diamond layouts under the conditions of different packing densities. The obtained bulk pressure coefficients of a block located in various staggered arrays showed clear dependency of packing density. This result suggests the importance of the consideration for the reduction of wind-driven cross ventilation due to neighborhood densely built-up area in building simulation coupled with ventilation model.
