Implementation of a rooftop recirculation parameterization into the quic fast response urban wind model

Abstract

Buildings change the local flow characteristics and introduce various complex flow features that have an impact on the transport and dispersion of airborne contaminants. Material released in the vicinity of a building may become entrapped in the various recirculation zones around a building altering the ground-level concentration. The Quick Urban & Industrial Complex (QUIC) dispersion modeling system has been developed to rapidly provide 3D wind and concentration fields around buildings in cities. A new rooftop recirculation parameterization has been implemented into the wind model and in this paper the scheme is evaluated by comparison of model output and experimental measurements of the mean flow above building rooftop. The wind-tunnel experiments included buildings of various width, length and height and an incident wind angle perpendicular to the front face of the building.
