Summary: | Laminar-turbulent transition mechanisms induced by a harmonic point source disturbance in a flat-plate boundary layer with adverse pressure gradient are investigated by fourth-order accurate spatial direct numerical simulation based on the complete three-dimensional Navier-Stokes equations for incompressible flow. The disturbance is introduced into the two-dimensional base flow by time-periodic simultaneous blowing and suction within a circular spot at the wall to quietly mimic the momentum input by an active loudspeaker below a hole in the surface in respective experiments. |
