BY : CHAM Consultancy Team - J P Edwards
FOR : Consultants in Environmental Services Ltd.
DATE : 1993 PHOENICS Version : 1.6.6
DETAILS :
- Three-Dimensional, Steady flow
- Cartesian computational grid
NOTES :
- PHOENICS has been successfully used to study the dispersion effects of
pollutants accumulated within road tunnels
- Also, it examines the effect of these pollutants outside the tunnel
portals, assuming various wind conditions
- The tunnels are rectangular cut-and-cover tunnels, carrying two
opposing traffic streams
