Abstract

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.
