Title: Flow past a cylinder at a Reynolds number of 10,000 with plasma-based flow control

Description: Large-eddy simulation of flow past a circular cylinder at a Reynolds number of 10,000 with plasma-based flow control. Dielectric-barrier-disharge plasma actuators are mounted on the top and bottom of the cylinder, extending 30 degrees in the circumferential direction. These produce a wall-jet-like flow and Coanda effect, which mitigates vortex shedding and the associated large amplitude unsteady forces. The solution was obtained with a sixth-order accurate numerical method using 24 million grid points.
