Two unsteady numerical techniques, LES and PANS, with difference computer requirements, were used for prediction of the flow around a tall finite cylinder. The well resolved LES was found to predict the flow in agreement with previous experimental observations, while PANS was found to suffer from the combination of k - epsilon model in conjuction with wall function close to the wall of the cylinder and too coarse resolution.

Nyckelord: finite cylinder, LES, PANS
