| Research Abstract |
Static pressure and velocity fluctuations are measured in high-Reynolds number turbulent boundary layers. It is found that the mean pressure and root mean square profiles are scaled by inner/outer typical velocity scale and length scale independent of Reynolds numbers. Anisotropy caused by the mean velocity gradient is analyzed by linear response theory in the inertial range. The universal anisotropic constants are derived theoretically and they are determined by the experiment.
