The deflection of plane turbulent jets by convex walls

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.
