Organized by the AIAA Air Breathing Propulsion System Integration Technical Committee

The focus of the workshop will be on assessing the accuracy of CFD in obtaining air breathing system performance and flow structure to include nozzle forces, plume surveys, subsonic inlet recovery and distortion, and high-speed inlet performance. Experimental data are available for the test cases; however, the CFD studies will be performed as a blind trial and compared with the experimental data during the PAW04 workshop.

Documents outlining required data will be provided for multiple cases featuring isolated inlets, isolated nozzles, nozzle with aft deck, and a high-speed inlet. A statistical framework will be used to assess the CFD results.

Baseline computational grids will be provided for CFD solvers. However, geometry will also be available to those interested in developing their own meshes. Participants may run one or all of the test cases and present their results.

The workshop provides an impartial forum to present findings, discuss results, exchange ideas, and evaluate the effectiveness of existing computer codes and modeling techniques for propulsion CFD.

Topics include:

  • Analysis of flow in a diffusing S-duct with and without AIP instrumentation, and with and without flow control
    • Comparisons of AIP total pressure recovery and distortion both steady-state and dynamic
    • Comparisons of steady-state surface static pressure distributions
  • Analysis of flow in a high aspect ratio nozzle with and without an aft deck
    • Comparisons of surface pressures
    • Comparisons of plume statistics
  • Analysis of a high speed external compression inlet
    • Comparisons of surface pressures
    • Comparisons of total pressure recovery and distortions
