The three-dimensional laminar asymptotic boundary layer with suction

Three-dimensional laminar flow over a flat plate with uniform suction is considered for a specific class of outer-flows. A series solution of the boundary-layer equations is obtained for the asymptotic case, that corresponding to transverse velocity which is everywhere constant. The limitations of the asymptotic solution are examined in terms of existing theory and experimental data for the analogous two-dimensional case. A numerical example, typical of aircraft flight parameters, is discussed in relation to the analogous impermeable wall case.
