The main objectives of the current project are therefore:
- To control turbulent wall bounded shear flow effectively from a more fundamental level by investigating directly the behaviour of Reynolds stresses and their response to the manipulation of the dynamic components of the flow
- To conduct both experimental tests and computational simulations to extract reliable flow physics, including Reynolds stresses, for a number of active flow control devices
- To explore large scale unsteadiness (unsteady jets, wakes and vortices) produced from the capability of these devices forto provide effective control of the dynamic components, and hence the Reynolds stresses, within the shear layers associated with large scale wakes and separations
- To identify key strategies that enable efficient control of dynamic fluid structures within shear layers and to design and optimise these devices for separation control (higher shear) and drag reduction (lower shear)
- To demonstrate the most promising device/devices at relevant scale, the ability to efficiently increase or decrease the Reynolds stresses
- To investigate the application of this capability within an aircraft context
- To foster further collaboration between European and Chinese researchers in the key technology area of flow control for the benefit of the civil aircraft industries on both sides.
