Effects of Periodic Local Forcing on a Turbulent Boundary Layer
주기적 국소교란이 난류 경계층에 미치는 영향

Abstract
An experimental study is performed to analyze flow structures behind a local suction/blowing in a flat-plate turbulent boundary layer, The local forcing is given to the boundary layer flow by means of a sinusoidally oscillating jet issuing from a thin spanwise slot at the wall. The Reynolds number based on the momentum thickness is about
