Abstract

The characteristic feature of flow around an extended body is the interaction of the thickened boundary layer with the external nonviscous flow. This phenomenon becomes more significant at low Reynolds numbers and high Mach numbers. Theoretical investigation of this interaction is difficult because of the presence of shock waves, which are characteristic of hypersonic velocities; the position and curvature of these shock waves depend on the state of the boundary layer developing in conditions of pronounced vorticity of the external flow. With increasing rarefaction of the flow, the problem begins to take on an elliptic character, and this necessitates the use of methods of investigation of more general form than the classical boundary-layer theory.
