Abstract:
Analytical and experimental studies were conducted to provide information regarding the characteristics of power jet reattachment in wall-attachment digital amplifiers. The experimental studies included investigations of the effect of control flow on the power jet reattachment location for both single- and double-boundary-wall configurations having various wall lengths and the spreading rate of the jet boundary enclosing the separation bubble for single-boundary-wall configurations. These studies were conducted for both subsonic and supersonic jet Mach numbers. The analytical studies included an investigation of techniques for predicting the effect of control flow on the power jet reattachment location for single-boundarywall configurations having a boundary wall of infinite length. An empirical correlation of the experimental results obtained for the infinite length, single-boundarywall configurations is presented from which the effect of control flow on the reattachment location can be estimated. Also presented is a generalization of the effect of terminating the boundary wall.
