Abstract

Time-depending air flows around a 4:4:1 square cylinder are simulated with LES. The obtained time-averaged velocity distributions show good accordance with wind-tunnel experiments. It is also shown that time-averaged scalar velocity distributions can be reproducedwith using the magnitude of time-averaged velocity vector and fluctuating velocity.
