摘要: The present study considers an investigations of urban flow in complex morphological street network that is coincidentally similar to ancient Algeria city namely Ghardaia. This shows how one can apply a CFD model simulate the air behavior this area. The computational fluid dynamics software, Fluent 6.3.26 employed determine velocity field traversing streets. Information on layouts buildings selected area contained Google earth. The AC3D 6.5.28, with its programming facility, has been used extract geometry each building polygon under research. These are then cleaned by Materialise Magics and input into Gambit 2.4.6 Fluent’s mesh generation software construct simulations. Finally, steady-state simulation results drawn from profile.
