Vortical structures behind Re=89000 cylinder


We are developing the LES capability to predict the sound radiated by turbulent flows. A novel end-cap correction methodology for the Ffowcs-Williams Hawkins methodology has been developed that enables the acccurate prediction of radiated sound without spurious end-cap effects. The approach has been applied to predict the far-field sound produced by a variety of flows such as bluff bodies, sharp trailing edges and airfoils.
