Paper Abstract

The results of an experimental investigation of isothermal swirling flows in a model of a coaxial dump combustor are presented. A set of three constant angle swirlers were designed and fabricated for this aspect of the study. A two component LDV system was used to obtain the velocity measurements of the flowfield. The detailed data base is provided for the development of turbulent closure models and the CFD code validation for the ramjet or turbojet applications. The results show the effects of the swirl strength on the flow characteristics, enhanced turbulent mixing and the resulting shortened corner recirculation zone.
