Mixer-ejector noise-suppressor model
DE Tew, BS Teeple, IA Waitz - Journal of propulsion and power, 1998 - arc.aiaa.org
ATYPICAL mixer-ejector noise suppressor is depicted in Fig. 1. These suppressors entrain
cold secondary air into a duct and mix that air with a hot, fast primary stream. This mixed …

[PDF][PDF] Modeling of mixer-ejector nozzle flows
AK Fung - 1995 - dspace.mit.edu
An analysis was formulated to describe the flow within a mixer-ejector nozzle. The analysis
was used to predict the mass flow pumping and thrust performance of mixerejectors typical …
