Abstract

Physical Modelling of Vehicle Emissions in Respect of Car-Induced Turbulence A contribution to subproject SATURN A. Kovar, B Leitl, J Liedtke and M. Schatzmann Meteorological Institute, University of Hamburg, Bundesstr. 55, D-20146 Hamburg, Germany The concept and first results of a basic study are presented to simulate the dispersion of car emissions in a wind-tunnel. The aim is to develop a method which allows the correct scaling of pollutant dispersion due to car traffic in wind-tunnel models, i.e. the effects of car-induced turbulence. Introduction Air pollution due to car-traffic is still a major environmental problem. European regulators have recognised its importance (see Ambient Air Quality Guideline, 96/62/EC, which is presently supplemented by daughter directives). Some of these daughter directives focus directly traffic-generated air pollutants. The execution of these regulations require
