FREE INTERACTION OF THE FLOW IN A LAMINAR BOUNDARY LAYER WITH AN UPSTREAM MOVING EXPANSION WAVE

  • Published:
Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

The processes of interaction of an expansion wave with the flow in a laminar boundary layer are studied with the use of the theory of free interaction. Numerical solutions of a nonlinear problem are found for various values of the dimensionless velocity of wave motion. Distributions of pressure-induced friction stress on the surface are obtained.
