    Physical Modelling of Urban Roughness using Arrays of Regular Roughness Elements

    The aerodynamic behaviour of large urbanagglomerations must be represented in increasingly greaterdetail, as large-scale numerical weather prediction and airpollution dispersion models are refined. The present...

    Near Field Dispersion in the Urban Environment - A Hydraulic Flume Study

    The dispersion of material released from a point source immediately upwind of an obstacle array has been examined in a hydraulic flume with a low level of background turbulence. The main purpose of the experim...

    Turbulence measurements from a plane air jet with buoyancy induced curvature

    An experimental investigation of the turbulence structure of a heated plane air jet discharged at various angles into quiescent surroundings is described. Hot-wire anemometry was used to obtain the profiles of...

    Mean flow characteristics of a turbulent plane jet with buoyancy induced curvature

    An experimental investigation of heated vertical and inclined plane air jets discharged into quiescent surroundings is described. A unique feature of this data is that Pilot tube measurements were used to defi...

    A Comparison of Some Plume Dispersion Predictions with Field Measurements

    During four seasonal periods in 1977, measurements of the rise and spread of the powerhouse plume of the Suncor plant in the tar sands area of Alberta, Canada were collected, using both ground-based photograph...
