Distinctive Features of Flow in the Hypersonic Boundary Layer in the Vicinity of the Plane of Symmetry of a Planar Wing Having a Bend of the Leading Edge

详细

The flow in the three-dimensional laminar boundary layer in the vicinity of the plane of symmetry of a semi-infinite planar wing having a bend of the leading edge is investigated in the case of strong interaction with the external hypersonic flow. The flow functions are asymptotically expanded in power series in the angular coordinate in the vicinity of the plane of symmetry. The corresponding boundary value problem for the principal terms of the expansion is formulated and solved. The possibility of the existence of several solutions in the vicinity of the plane of symmetry is shown. The sweep angle effect on the distinctive features of the flow is considered.
