An assessment of turbulence models for the prediction of flow past a circular cylinder with momentum injection

Moving Surface Boundary-Layer Control on the Wake of Flow around a Square Cylinder

“…Finally, the wake turbulence is completely suppressed at ζ = 1.5. Muddada and Patnaik [36] compared the wake characteristics of a flow past an isolated circular cylinder, with momentum injection in the subcritical Re range. The numerical flow visualization through streaklines and streamlines clearly demonstrated the effectiveness of the rotating-type actuators in modifying the turbulent vortex structures.…”

Experimental Investigation of Flow Structure Downstream of Permeable Cylinders

“…At active control methods, there is an energy input into the flow region while passive control methods are based on the geometrical adjustments. Plasma actuators (Corke et al, 2010), synthetic jets (Feng and Wang, 2012;Akansu and Fırat, 2010), feedback controls (Muddada and patnaik, 2010;Hiejima et al, 2005) and suction and blowing (Li et al, 2003) are some of the active control methods. On the other hand, many passive control methods are used at the studies since applying passive control methods are easier than that of the active control methods.…”
