A MATHEMATICAL MODEL OF WIND FLOW, VEHICLE WAKE, AND POLLUTANT CONCENTRATION IN URBAN ROAD MICROENVIRONMENTS. PART II: MODEL RESULTS

摘要

Theoretical formulations of the proposed model for prediction of pollutant dispersion in micro- environments was previously introduced in part I of this paper (Karim and Matsui, 1998). This paper dis- cusses the new model findings and presents model evaluation results. This paper first explains the current problems that the road environment plays in employing field data for wind and temperature collected along a road north of Nagoya, Japan. A complete simulation is done on wind components in street-canon and wind distribution, including vehicle wake effect, and is evaluated with experimental results.
