Hybrid Laminar Flow Over Wings Enhanced by Continuous Boundary-Layer Suction

The numerical analysis of continuous boundary-layer suction on a flat plate at zero angle of attack is the focus of this study. A uniform flow is prescribed upstream of the plate. The governing equations, the Navier-Stokes and continuity equations are presented by the vorticity-stream function formulation. A transformation is made from the physical to the computational domain and the resulting equations are solved numerically by the ADI and SOR methods, respectively. Reynolds numbers from 10³ to 10⁴ are considered. A second-order upwinding scheme is employed to numerically stabilize the solution. A comparison is made between flows with and without suction. Preliminary results are presented for the solution behavior as a function of such parameters as Reynolds number, grid resolution and numerical representation of the boundary conditions.
