The aim of this research was to investigate the flow pattern around a test room which is used for natural ventilation studies. The test cell effectively represents an in-fill development of a low-rise building located adjacent to high-rise buildings. When considering natural ventilation in a building in such a location it is beneficial to understand the local wind flow patterns resulting from the impact of the surrounding buildings on the prevailing wind conditions.
This paper presents an investigation into natural ventilation in the field of computational fluid dynamics using in particular rather rough mesh cells. The CFD results were then compared to the wind tunnel results obtained by Gouin at the Centre Scientifique et Technique du Batiment ( CSI'B) in Nantes. The role of eaves, and that of window configuration on windward and leeward sides of buildings was also investigated to search for a better interior airflow.
This paper describes an analysis using the BRE Pollution Dispersion Wind Tunnel to estimate pollution concentration patterns on buildings in urban arrays due to local line sources of pollution, typical of vehicular traffic emissions. The experimental procedure involved measurements of both pressure and concentration patterns on building forms in urban arrays, intended to provide information on the ingestion of pollutants into buildings in urban areas.
