Abstract :The flowfield around a high-rise building model placed within the surface boundary-layer was analyzed using various revised k-ε models, and these results were compared with the result of DSM and the experimental data. The standard k-ε model could not reproduce the reverse flow on the roof. This drawback was corrected by all revised k-ε models and DSM tested here. However the revised k-ε models except for the model proposed by Durbin overestimated the reattachment length behind the building in comparison with the standard k-ε model. Among the computations using various turbulence models compared here, the result with the Durbin’s revised k-ε model showed the best agreement with the experiment.
