High Reynolds number turbulent boundary layer measurement is performed in the RTRI ’s low-noise wind tunnel in Maibara Japan. The momentum thickness Reynolds number Rθ is up to approximately 8×104. Mean velocity statistics are compared with those

To better understand high Reynolds number zero-pressure-gradient turbulent boundary layers detailed hot-wire measurements of the mean and fluctuating streamwise velocity are made in RTRI ’s low-noise wind tunnel in Maibara Japan. The momentum thick

We experimentally investigate the unstable behavior of a large scale hollow-type streamwise vortex which has a solid-rotation type distribution of vorticity existing only in an annular region initially, focusing on how the large scale vortex breaks d

Two-dimensional local wall suction is applied to a fully developed turbulent boundary layer such that near-wall turbulence structures are completely sucked out, but most of the turbulent vortices in the original outer layer can survive the suction an

The instability of the three-dimensional high-shear layer associated with a near-wall low-speed streak is investigated experimentally. A single low-speed streak, not unlike the near-wall low-speed streaks in transitional and turbulent flows, is produ

The aim of the present study is to contribute to the operation and control of wind turbines situated in mountainous areas, which often suffer from over-speed due to highly gusty mountainous winds with high shear. By adding an electric load-brake to c

Three-dimensional growth of Tollmien-Schlichting (T-S) waves excited at two frequencies are examined both experimentally and numerically in plane Poiseuille flow. The two T-S waves excited have nearly the same in amplitude and their frequencies (or w
