Variable-Area Ejector Development
Abstract
An experimental investigation was conducted to determine the performance of a variable-area ejector. Test equipment consisted of various fixed-geometry primary driving nozzles and either a constant-area or a conical- converging mixing duct attached to a conical-diverging exit section, which was equipped with a conical centerbody. Axial movement of the conical centerbody varied the minimum area of the ejector. Five primary driving nozzle geometries were used. Both steady-state and transient performance characteristics of the ejector configurations are presented. A constant-area (no centerbody) ejector having a diameter equivalent to that of the variable-area ejector mixing duct was also evaluated. In general, the performance of the variable-area ejector configuration exceeded that of the constant-area ejector.
