Abstract

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