Turbulent air flow around a building has been simulated by means of three dimensional Large Eddy Simulation. In this type of siumlation, the predicted wind velocity fluctuates continuously with position and time. The results of the simulation are compared with those of wind tunnel tests with regard to air flow pattern and various statistical quantites (i.e. velocity spectrum, turbulent intensity, integdral scale and so on). It is confirmed that the correspondence between the numerical simulation and the wind tunnel experiment is rather good.
