Transition Modeling Workshop: Future Activities, Goals, and Organization
"Explore the future activities, goals, and organization of a Transition Modeling Workshop, discussing key topics such as promoting improvements to the state of the art, engaging model developers, and structuring the organizing committee. Join the discussion on transitioning from SciTech 2020 and enhancing the field of transition modeling."

CFD Transition Modeling DG Meeting 5:30 7:00 PM January 9, 2019 Seaport H
Agenda Introductions Presentations Doug Stefanski Future activities of the DG Workshop Pre-Planning Organizing committee Structure Test cases 2
Future Activities of DG What do we do after the SciTech 2020 workshop? Do we shift to a working-group model? Are we successfully promoting improvements to the state of the art? If not, what can we do better? 3
Workshop Organization Organizing Committee Jim Coder (U. Tennessee) Doug Stefanski (U. Tennessee) Andreas Krumbein (DLR) Meelan Choudhari (NASA Langley) Jim Baeder (U. Maryland) Marie Denison (NASA Ames) Matt Tufts (AFRL) Greg Delattre (ONERA) 4
Goals Goals of the workshop Verification of transition model implementation as is done with the Turbulence Modeling Resource cases Fully documented models necessary How to verify post-RANS (i.e. scale resolving)? Invite and encourage WMLES Lattice-Boltzmann Need to engage this community Hybrid RANS/LES with transition Data analysis of all participants contributions Submission templates need to be defined Encourage risk taking Want to know where the models fail Expose the deficiencies 5
Test Cases T3A/T3B/T3A-/S&K Verification T3C series Grids needed Airfoil Verification (S809 and NLF(1)-0416 previously) Unsteady transition 2D pitching airfoil SBLI Transonic buffet Virginia Tech cylinder/airfoil Crossflow 6:1 Prolate Spheroid TU Braunschweig Sickle Wing HIFiRE-1 Conditions defined in AIAA paper Encourage/inspire model developers for high speed NLF-CRM NLF(2)-0415 scale resolving 6
Webhosting Meelan Choudhari has offered the use of https://transitionmodeling.larc.nasa.gov/ Opportunity to create a Transition Modeling Resource as an analog to the Turbulence Modeling Resource 7
Workshop Logistics Structure Presentations Breakout sessions? Open forum? Length? Guest speakers? Industry perspective to make clear needs from their side E.g. certification by analysis 8
Next Steps Case Description Document Build on one from 2018 SciTech special session Grid Generation Unstructured Structured, overset High-order? Cases that already have grids: Flat-plate cases (all) S809 NLF(1)-0416 Prolate spheroid (many levels unstructured, 1 level structured) 9
