Drag Bookkeeping Strategies for Conventional and Unconventional Nozzles

Alister Simpson, Marco Geron

Research output: Contribution to conferencePosterpeer-review


This presentationinvestigates the development of a coherent and robust methodology for drag bookkeeping strategies considering conventional and adaptive area nozzles. The methodology is developed through the use of 3D RANS simulations of the Dual Flow Separate Reference Nozzle, and of two alternative adaptive nozzle area nozzle geometries developed under the AvAUNT project (EU Clean Sky 2). The methodology investigates the possibility to develop consistent drag bookkeeping strategies considering only limited data availability representative of wind tunnel testing.
