Research Abstract |
We investigate the control of self-sustained oscillating flows over an open cavity using a moving bottom wall. The three-dimensional incompressible Navier-Stokes equations are solved by direct numerical simulation. A series of simulation are performed for a variety of bottom wall velocity. The results show that velocity fluctuations and pressure fluctuations are suppressed due to the moving bottom wall of cavity. The control method by moving bottom wall can suppress self-sustained oscillating flows over cavity.
