摘要：

This study applied a Reynolds Averaged Navier-Stokes (RANS) approach with Renormalization Group (RNG) k-epsilon turbulence model on a simplified cubical array with uniform height arranged in square layout to study the effect of different opening position on wind-induced ventilation performance in urban area. Nine different cross opening configurations located on both leeward and windward facade are tested. The velocity distribution inside the building is observed as well as the ventilation rate for all cases. The result shows that openings located in the upper part of windward wall allows higher flow rate while openings positioned near the floor exhibits the lowest. (C) 2016 The Authors.
