A CFD VALIDATION ECOSYSTEM TO ADVANCE THE PREDICTION OF LOW-SPEED AERODYNAMICS
J.P. Slotnick, Boeing, United States
CFD validation efforts to advance the understanding of low-speed (high-lift) flow physics to ultimately enable a robust predictive capability are well underway within the international aerospace community, driven mainly through CFD prediction workshops. With the completion of the geometric definition of the High Lift Common Research Model (CRM-HL) in 2016, an informal consortium of organizations has been formed to create a CRM-HL “Ecosystem” to design, fabricate, and test a baseline set of CRM-HL configurations in several wind tunnels over a wide range of Reynolds numbers. These data will be used to validate existing and emerging CFD technologies. This paper will discuss the original genesis of the Ecosystem concept, the requirements that drove the technical efforts, and a summary of what has been accomplished and what is expected in the future.
