Preliminary Investigation of Dispersion of Pollutants in Model Building Wake Flows Using Bipolar Space Charge

摘要

The feasibility of using bipolar space charge to study the dispersion of pollutants in the wake flow region behind isolated model buildings in simple terrains in wind tunnels was investigated. A fast response time ion detector was developed. Results were obtained in the near, intermediate, and far wake flow regions. The method is shown to be capable of providing large quantities of information and good agreement is obtained between the near wake region results and full-scale trials.
