| Title: | METHOD AND APPARATUS FOR REDUCING TURBULENT DRAG | |||||||||||
| Abstract: | The systems and methods of the invention include systems and techniques for controlling a turbulent boundary layer from with a transverse traveling wave, oscillating at certain selected frequencies, amplitudes and wavelengths, to provide substantial reductions of drag. To this end, the systems and processes can include a boundary layer control system having an object with at least one surface exposed to a medium flowing over the surface. A plurality of excitation elements (252a, 254a, 256a, 258a) may be arranged on the surface and these elements are capable of exciting a traveling wave force field in a span-wise direction that is substantially parallel to the surface and perpendicular to direction of the flow. | |||||||||||
