Effects of feedback control on chaotic convection in fluid-saturated porous media
Thermal convective instability in a fluid-saturated porous layer heated from below and cooled from above is investigated theoretically using dynamical systems approach. A feedback control strategy with an array of sensors situated at the top plate of the fluid layer is adopted. The Galerkin trunca...

| description | Thermal convective instability in a fluid-saturated porous layer heated from below and cooled from
above is investigated theoretically using dynamical systems approach. A feedback control strategy with
an array of sensors situated at the top plate of the fluid layer is adopted. The Galerkin truncated approx�imation is employed to derive a low dimensional Lorenz-like model. It is shown that suppression or
enhancement of chaotic convection is possible via feedback control. |
