Microfabricated silicon surfaces for turbulence diagnostics and control

摘要

The active control of turbulene in a turbulent boundary layer is of great practical significance due to its portential impact on the kreduction of visous drag and the suppression of turbulence-induced nosie in a vehicle.However,it is also a very challenging bporblem.The emergin gtechnolgy of silicon microfabrication is being applied to develop a surface for tu rbulene diagnostics and ocntorl applciatiosn in hydrodynmic and kaerodynmaic vehicles.
