Ideal incompressible flow around a wedge tip
S. K. Betyaev Joukowski Central Aerohydrodynamic Institute, Zhukovskii, 140181
Abstract:
A planar analog of conical flows is considered: an inviscid incompressible fluid flow around a wedge tip. A class of conical flows is found where vorticity is transported along streamlines by the potential component of velocity. Problems of a wave “locked” in the corner region and of a flow accelerating along the rib of a dihedral angle are considered. By analogy with an axisymmetric quasi-conical flow, a planar quasi-conical flow of the fluid is determined, namely, the flow inside and outside the region bounded by tangent curves described by a power law. Conditions are found where vorticity and swirl produce a significant effect. An approximate solution of the problem of the fluid flow inside a “zero” angle is obtained.
Keywords:
ideal fluid, planar conical and quasi-conical flows, vorticity, unsteadiness.
