The effects of geometry and Reynolds number on the attachment of a jet to a convex wall and the mechanism of high pressure recovery in convex-walled amplifiers are investigated. The results are presented in terms of normalized parameters in a form suitable for comparison with theoretical results. Reasonably good agreement is obtained between the experimental results and those predicted theoretically by Gortler and Glauert, particularly for regions of flow away from the control port. The effects of the wall setback and control port are most pronounced in a region near the power nozzle where u sub m/u sub o attains values as high as 1.25.

This article presents results of experimental measurements for a two-dimensional incompressible plane jet by an inclined plate. The hysteresis has been observed as a different jet behavior (a free jet or a jet attached to a flat plate) depending on Author: Aldona Skotnicka-Siepsiak. The turbulent wall jet is also a basic flow of fundamental interest because of its two-scale character. The inner layer of the plane wall jet is similar to that of the turbulent boundary layer, while the outer layer resembles that of a free (plane) jet. The interaction of large turbulence scales in the outer layer with smaller scales in the.
