The flowfield around a high-rise building model placed within the surface boundary-layer was analyzed using various revised k-ε models. The accuracy of these models was examined by comparing their results with the experimental data. Among the computations using various revised k-ε models compared here, the result with the Durbin's revised k-ε model showed the best agreement with the experiment. The reason for the good perfomance of Durbin's model was discussed based on 'Realizability' of predicted results.
