要約

The turbulent flow around a square cross-section cylinder mounted in the vicinity of a solid wall has been simulated using Large Eddy Simulation. The results are compared to velocity and pressure field measurements. The predicted flow field captures essential features observed in experiments. The existence of spanwise jitter and secondary three-dimensional flow structures, which are generally not observed using the different time dependent RANS techniques, could be reproduced reliably.
