Two-Dimensional Turbulent Offset Jet-Boundary Interaction

Abstract

This paper presents a theoretical and experimental study of two-dimensional, turbulent jet-boundary interaction. The jet is discharged parallel to and offset from a solid wall in the presence of a secondary freestream. An integral approach which makes use of the entrainment concept is used to predict the jet characteristics. The theoretical model departs from previous studies by relaxing the constant base pressure and radius of curvature restrictions and treating both as variables in the preattachment region. In general, good agreement is observed between experimental and theoretical predictions.
