Abstract
Numerical simulations of the Stokes boundary layer over a three-dimens ional wavy wall are performed in order to investigate the role played by infinitesimal wall imperfections in triggering transition to turbul ence. Our results show flow patterns qualitatively similar to those ex perimentally detected. In particular the laminar, disturbed-laminar an d intermittent turbulent regimes are recovered. The characteristics of the above flow regimes are analyzed. (C) 1996 American Institute of P hysics.
