Abstract:

The goal of this study is to investigate the structure and the dynamics of unsteadytransient separated turbulent boundary layers. Central to the study is the characterization of the streamwise and spanwise fluctuating skin friction and wall pressure fluctuations in and around the separation zone. During the first year of the project, a photonic skin friction and wall pressure sensor will be implemented to measure directly and at the same spatial location the unsteady skin friction and wall pressure. The photonic sensor will be an extension of our previous sensor development efforts, which were limited to low to moderate-frequency wall shear stress measurements.
