Abstract
First experimental measurements of manipulation of the structure of a canonical zero pressure gradient turbulent boundary layer using a low frequency (compared to the viscous frequency) mechanical dynamic roughness are presented. "Dynamic" (or time-dependent) surface roughness is proposed as a method for both control and diagnosis of turbulent boundary layers.
