Many industrial products contain flow systems whose performance affects the overall product capabilities, especially the energy cost associated with their operation. Reduction of the energy cost may come primarily through the reduction of drag. The present work is focused on the development of smart surfaces that would provide a means for an effective management/re-arranging of flows. Surfaces that reduce the skin friction laminar drag, affect the drag by delaying/accelerating the laminar-turbulent transition and reduce the turbulent drag by re-arranging the bulk flow, as well as turbulence production, are sought.

许多工业产品都包含流体系统，其性能会影响产品的整体性能，特别是与其运行相关的能源成本。降低能源成本可能主要是通过减少阻力来实现的。目前的工作重点是智能表面的发展，这将为有效管理/重新安排流动提供一种手段。寻求减少表面摩擦层流阻力，通过延迟/加速层流-湍流过渡来影响阻力，通过重新安排大量流动来减少湍流阻力以及湍流产生的表面。
