Abstract

The intermediate wake of a circular cylinder at Reynolds number 3300 is studied by means of highly resolved large eddy simulations. The domain spans 100 cylinder diameters D downstream of the cylinder. The intermediate wake is taken here as the region between 6D and 50D downstream of the cylinder. Initially, the velocity deficit shows a marked decrease. This rate of decrease diminishes in the region 10D to 20D downstream of the cylinder centre. Thereafter, it starts to evolve following the far-wake behaviour. The wake half-width exhibits a marked increase in the region 20D to 40D. It is in this region where the von Kárman vortex street looses its coherence.
