Experimental Investigation of Turbulent Jet Attachment to a Convex Wall.
Abstract
The effects of geometry and Reynolds number on the attachment of an air jet to a circular convex wall and the mechanism of high pressure recovery in convex-walled amplifiers are investigated. The results are presented in terms of normalized parameters suitable for comparison with theoretical predictions. Extremely high pressure recoveries are possible in convex-walled amplifiers due to the particular velocity distribution and entrainment characteristics exhibited by flow attached to a convex wall. The wall setback and the condition of the control port have very little influence on the flow downstream of the initial attachment region. (Author)
