The Control of Separation from Curved Surfaces and Blunt Trailing Edges

Abstract

The project that was initiated in the fall of 1999 encompasses three exploratory studies: (1) A pulsed wall jet over a curved surface in the absence of an external stream (2) Pulsation emanating from a circular cylinder in streaming flow. (3) The application of active flow control to an airfoil having a divergent trailing edge. The report will cover all three experiments although most progress (beyond the exploratory stage) was made on understanding the wall jet flowing over a convex surface. Some of the experimental work on this project was initiated prior to the last funding period but data analysis took more time some of the results have been discussed in interim progress reports. The other investigations are still ongoing at a lower pace.
