Abstract

Understanding Flow Patterns at Street Canyon Intersections Using Wind Tunnel and CFD Simulations A contribution to subproject SATURN A. Scaperdas\ RN Colvile* and AG Robins* ^Air Pollution Group, T.H. Huxley School, Imperial College of Science, Technology and Medicine, SW7 2BP, London, UK ^ EnFlo, School of Mechanical & Materials Engineering, University of Surrey, The aim of article is to illustrate the main features of flow at street canyon intersections and how these can affect dispersion at a local scale, on the basis of experimental results from wind tunnel simulations. The work presented is part of an on-going research project funded by the UK Engineering and Physical Sciences Research Council. Introduction The street canyon (a street with buildings on both sides) has long been regarded as the fundamental building block of the complex street-building geometry of cities. The empha
