The aim is the numerical investigation of boundary conditions for suction through porous surfaces for hybrid laminar flow at the leading edge of an infinite sweep wing. Four different boundary conditions are tested. By boundary condition 1 (BC1) and BC2 the velocities at the boundary condition are set and the difference between this two boundary condition is the setting of the pressure. By BC3 and BC4 the suction velocity is set by the pressure at the boundary condition and the pressure is as long as iterated until the target mass flux is reached. In BC4 the tangential velocity is set to zero in contrast to BC3. Only the simulation with BC2 gives good results of suction in comparison to experimental data.
