摘要: This paper presents a comparative assessment of two urban morphologies representing the transformations that occurred between 1976 and 2013 in downtown Rio de Janeiro. The work documents impact city morphology changes on air flow pattern, which is known to change energy needs at scale city. Special attention dedicated comfort pedestrian level potential for natural ventilation building reference. study was performed by means numerical simulations based RANS k-ϵ turbulence model. results show an increment wind velocity pressure difference rise facades. New high-rise buildings increase stagnation area leeward region, boundary layer height, level.
