Wind Flow And Pollutant Migration Predictions

BSRIA Microclimate centre was commissioned by Zisman Bowyer and Partners to carry out a CFD study of airflow and chemical dispersion at a research centre.

The ZBP site consisted of a number of research laboratories, some of which contained fume cupboards. The aim of the study was to predict wind flows over the site and the resulting concentration of chemicals in the air after a spillage.

Results from the calculations allowed the risks posed by the flues to be determined. Therefore alternative designs could be simulated and the visual impact of the flues reduced.

BSRIA conducted repeated calculations with differing wind speeds and directions for a number of alternative designs of flues. As a result, ZBP devised a solution which satisfied safety requirements as well as being aesthetically acceptable. This was essential in order to obtain planning permission.
