Abstract :The flowfields around a front-step and a cubic shaped building model placed within the surface boundary layer were analyzed by using various k-ε models; namely standard k-ε, Durbin’s revised k-ε and revised k-ε with mixed time-scale concept. The calculated results are compared with those of wind tunnel experiment. Turbulent kinetic energy k around the windward corner is overestimated by the standard k-ε and the Ω type revised k-ε models, while it is improved by the S type model and the model proposed by Durbin. However, all revised k-ε models overestimate the reattachment length behind the building in comparison with the experimental data.
