These two modifications to the dispersion coefficients were benchmarked and justified in the ARCON96 code documentation.

WebFour regions can be identified: upwind, top, wake and recovered region. Although the inlet flow is recovered at a very large downwind distance (X=20H), only at the top of the building is a significant increase of Ct2 … Web2.1 General Building Wake Effects Wind passing over and around buildings creates a complicated dispersion pattern. Figure 1 (Wilson, 1979) shows a cross section of the flow over a building with the wind perpendicular to the face of the building. The recirculation cavity (Zone I-ZI) is created when the flow separates from the upwind edge of the ...
