2-Day Workshop

AIAA SciTech 2021 Nashville, Tennessee USA

January 9-10 2021

General Objectives

  • Establish best practices for the prediction of S&C derivatives with RANS or DES – based CFD and to assess the limitations of these CFD methods when those best practices are applied
  • Provide an impartial forum for evaluating the effectiveness of existing computer codes and modeling techniques using RANS and DES solver
  • Identify areas in need of additional research and development

Focus of Workshop I

The inaugural workshop will use the ONERA version of the NASA/Boeing Common Research Model (CRM). It includes the wing, body and horizontal tail as well as a vertical tail designed by ONERA. This model has been tested in a wind tunnel with longitudinal test results having been published. There also exists unpublished data for this model at small sideslip angles. In this workshop, participant predictions of yawing moment, rolling moment and side force at sideslip will be compared to this unpublished data. Optionally, participants will predict the effects of the wind tunnel support sting on these moments and force.

Key Dates

Test Cases

Required
Case 1:2d Code Verification Study
Case 2:CRM in Sideslip Grid Convergence Study (single condition on a family of grids)
Case 3:CRM Static Lateral Directional Stability (3 solutions on 1 grid)
Optional
Case 4:Wind Tunnel Sting Increments
Case 5:Participant Generated Grids

Grids for all cases will be provided, but participants are encouraged to build their own grids using 'best practice' techniques. IGES and STP models are available for grid construction. Grid size requirements will be available on the workshop website. All grids used for results presented at the workshop must be submitted to the SCPW Organizing Committee to be made available to all interested parties.

General Information

  • This workshop is open to participants worldwide. Efforts will be made to ensure representation from all areas of industry, academia and government laboratories.
  • Participation in the prediction studies is not required to attend the workshop. Everyone is welcome!
  • Open forums will be included in the workshop to discuss the solutions and modeling techniques.
  • Results will be made available after the workshop in an AIAA paper.
  • A nominal registration fee will be required for attendance.
