Summary
Measurements and calculations of the pressure and velocity characteristics of a two-dimensional boundary layer approaching separation are presented and compared. The velocity measurements were obtained with a combination of impact probes, stationary and flying hot wires and quantify, for example, the rapid growth of the boundary layer as separation is approached. The calculated results were obtained with a combination of potential flow and boundary-layer equations. The Laplace equation was solved, in finite-difference form, to obtain the locations of the iso-vorticity and iso-stream function lines throughout the flow; the potential velocity and pressure distributions were subsequently obtained and used as boundary conditions for a finite-difference solution of the boundary layer equations with a Reynolds stress turbulence model. The relative importance of conservation of momentum, normal to the surface, and of the interaction of the viscous and inviscid flow equations are examined.
