The structure of jets from notched nozzles

  • S. S. Pannu (a1) and N. H. Johannesen (a1)


Jets from notched nozzles are investigated by schlieren photography and pressure traverses. It is demonstrated that the dominant feature of the flow which determines the structure far downstream is the trailing vortices shed from the swept edges of the notches.
