Passive flow control
WebA passive flow control around a two-dimensional D-shaped bluff body is studied at a Reynolds number of 13 000 using Large Eddy Simulation with the Coherent Structure Model (CSM). A small circular control cylinder located in the near wake region behind the bluff body is employed as a local disturbance of the shear layer and the wake. Numerical ... WebMar 9, 2024 · Fig. 3.
