Abstract

This study aims to verify prediction of pollutant concentration in urban area based on wind <br>tunnel  experiment  by  comparing  experimental  results  for  a  small-scale  model  of  Tokyo <br>Polytechnic  University  area  with  field  measurement  data.  Wind  tunnel  experiment  was <br>conducted  under  various  conditions  of  wind  velocity  and  pollutant  emission  rates  to <br>investigate effects of these factors on the prediction accuracy. It is showed that normalized <br>non-dimensional  concentration  obtained  by  wind  tunnel  experiment  agreed  well  with  the <br>field measurement data. It is also confirmed that normalized non-dimensional concentration <br>is nearly independent of wind velocity and pollutant emission rate.
