Abstract
This study aims to validate prediction of pollutant dispersion in urban area based on wind tunnel experiment. For this purpose, wind tunnel experiments and filed measurements of tracer gas dispersion were conducted in the campus of Tokyo Polytechnic University, and their results were compared. In addition, wind tunnel experiment was carried out under various conditions of experimental model scale, wind speed, and pollutant emission rates to confirm similarity law. The normalized concentration obtained by the wind tunnel experiments agreed well with the field measurement data. It was also confirmed that the normalized non-dimensional concentration was nearly independent of experimental model scale, wind speed, and pollutant emission rate. keywords: pollutant dispersion, field measurement, wind tunnel experiments, similarity law
