{Numerical Simulation of the Flow Around a Tall Finite Cylinder Using LES and PANS
Poster (konferens), 2008

Two unsteady numerical techniques, LES and PANS, with different 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 $k - \varepsilon$ model in conjuction with wall function close to the wall of the cylinder and too coarse grid resolution.
