A varied preview from the papers represented in this selection, with every available option.
Air flowing over a smooth cylinder of diameter 30 cm in a wind tunnel produces a two-dimensional laminar boundary layer that separates from the surface of the cylinder. The surface of the cylinder is then roughened with sand paper so that the boundary layer turns turbulent. The location of the point of separation will
