TITLE : EXHAUST DISPERSION NEAR IN A STREET CANYON

FOR : Industrial client

PHOENICS version: 3.1

DETAILS :

The three-dimensional wind flow distribution and pollutant dispersion have been predicted for terrain and around a group of buildings, forming part of a social building project in Thrace, Greece. A PHOENICS to AUTOCAD and vice-versa interface was used both for the geometrical input to the model and the interpretation of the results directly into AUTOCAD by non-CFD users.

Pictures are as follows :

Ground-level toxic-gas concentration

Ground-level toxic-gas concentration; another case

NOx dispersion near road interchanges

Velocity vectors in the vicinity of buildings, imported from PHOENICS into AUTOCAD

Another case of the same nature plus NOx contours
