Title

Effect Of Inclination And Compound Angle On Turbulent Quantities Following A Single Cylindrical Jet In Crossflow

Abstract

This is an experimental investigation into the effect of inclination and compound angles on the variation of mean/turbulent velocity profiles for a single cylindrical jet issuing into a turbulent boundary layer. Power spectral densities and extensive velocity measurements are made in the near field region of a discrete film hole exit, to determine how the hole orientation affects turbulent length scales and aerodynamic performance. Inclination angles of 30° and 90° are tested, with compound angles of 0° and 180°, while the hole L/D for each angle is fixed at 10. The measurement domain extends from x/D=0 to 2, y/D=-2 to 2 and z/D=0 to 2 at a nominal blowing ratio of M=1.42. This data represents an extension of the flow measurements previously available in literature. Also, the effect of hole orientation on turbulent length scales provide relations for easy determination of boundary conditions for computational work. © 2013 by the American Institute of Aeronautics and Astronautics, Inc.
