J Modeling of flow and dispersion characteristics in typical urban building configurations with the fast-response model QUIC P. Kastner-Klein*, J.V. Clark 1School of Meteorology, University of Oklahoma, Norman, Oklahoma, USA 1. INTRODUCTION: Many studies have shown that an increase in urbanization has been observed worldwide, and. the variations in flow and dispersion around individual b uildings or groups of similar buildings have been mostly av eraged out. Wind flow models de veloped for. In addition, pollutant concentration distributions also depend upon location and physical characteristics of the pollutant source. Overall fluid-flow complexity and variability from site to site have stimulated the development and use of physical modelling for determination of flow and dispersion in many wind-engineering by: We present experimental and theoretical investigations into the problems of wind flow and scalar dispersion within and around a group of buildings. Keywords Wind Tunnel Atmospheric Boundary Layer Bluff Body Boundary Layer Depth Plume Dispersion.

Modeling air pollutant transport and dispersion in urban environments is especially challenging due to complex ground topography. In this study, we describe a large eddy simulation (LES) tool.   Pergamon A tmospheriEnvironment V ol. 30, No. 8, pp. d , Published by Elsevier Science Ltd Printed in Great Britain (95) A COMPARISON OF NUMERICAL AND PHYSICAL MODELING OF STABLE ATMOSPHERIC FLOW AND DISPERSION AROUND A CUBICAL BUILDING Y.

› Study of the effect of atmospheric stratification on flow and dispersion in urban environment › Revision of the VDI guideline for physical modelling of flow and dispersion phenomena in the atmospheric boundary layer › Wind tunnel measurement of flow and pollution dispersion around consecutive two ridged hills - Bao-Shi.   CFD simulations are known to be very sensitive to many physical and numerical parameters. Many previous studies have analyzed the factors that influence RANS modeling, but few have considered how these factors affect LES modeling. This study investigates the factors that influence the LES modeling of flow and dispersion around an isolated building. The objective of PHYSMOD workshops is to bring together the community active in physical modelling of flow and dispersion in wind tunnels or water channels. It is intended to discuss, assess and report on the state-of-the art of relevant experimental work in this field, define directions of future research and encourage wider collaboration. understanding of the complex flow and dispersion processes in urban areas, and the generation of reliable datasets for evaluation of numerical models capable of simulating urban scales. Such models are needed as fast response tools in the case of releases of chemical or biological agents in an urban environment. An overview of the.
