Summary

Direct numerical simulations based on the complete Navier-Stokes equations are employed to explore the effects of suction holes on the generation and amplification of Tollmien-Schlichting waves in a flat plate boundary layer. The Navier-Stokes equations are used in vorticity-velocity form. Periodicity is imposed in spanwise direction; all other spatial derivatives are discretized with fourth order compact differences. An explicit fourth order Runge-Kutta scheme is employed for the time-integration of the vorticity transport equations. Suction is applied through a row of holes aligned in spanwise direction. Results are presented for suction holes with two different diameters, and for suction through a slot.
