本文讨论了湍流的主动控制，以减少表面摩擦，强调成本效益。通过引入性能指标，如净节能率和控制增益，我们评估现有的控制算法，真正的能源saving.We审查最近的尝试，以降低成本，伴随着实际应用，并讨论在开发更实用的控制算法的剩余问题。
This paper discusses the active control of turbulence for skin friction reduction with an emphasis on cost effectiveness. By introducing performance indices such as the net energy saving rate and the control gain, we assess existing control algorithms for true energy saving.We review recent attempts to reduce costs accompanying practical applications, and discuss remaining issues in developing more practically applicable control algorithms.
