Effect of non-harmonic inflow perturbations on unsteady separation from a circular cylinder

What is it about?

The study illustrates the effect of incoming flow perturbations of different waveforms on the unsteady flow separation from a circular cylinder and consequent phasing of the drag and lift forces on the body,

Why is it important?

This work shows that slight modifications on the waveform of the relative velocity between a free stream and an oscillating body can have a considerable impact on the phasing of the fluid forcing and thereby on the energy transfer between the fluid and the body.

Perspectives

Dr Efstathios Konstantinidis

This work demonstrates a way to achieve better flow control by adjusting the waveform on one hand while it also highlights the importance of nonlinear effects on subtle fluid dynamic phenomena.
