Abstract

This work concerns the turbulent flow generated around a thick flat plate to study the relationship between instantaneous flow structures and the unsteady pressure field. LES results compare favorably to experiments thanks to using a high order scheme. Mean and fluctuating quantities are very well predicted in both the detachment and the reattachment regions. Dimensionless frequencies, characteristic of flapping and shedding phenomena, have also been recorded that are in agreement with experiments.
