Abstract :The wind tunnel experiment for two rectangular buildings model with the scale ratio of 2:1:l in parallel arrangement with oblique wind angles was carried out. The experimental database was used for validation for the prediction accuracy of CFD technique applied for this flowfield. The special attention was paid to the velocity distribution in strong wind region near ground surface for the validation. The CFD analysis with two turbulence models, i.e., the standard k-ε model and the modified k-ε model, was conducted in order to clarify the prediction accuracy of CFD methods in comparison with the experimental database.
