Recommendations for Future Efforts in RANS Modeling and Simulation

Bush, Robert H. and Chyczewski, Thomas S. and Duraisamy, Karthikeyan and Eisfeld, Bernhard and Rumsey, Christopher and Smith, Brian R. (2019) Recommendations for Future Efforts in RANS Modeling and Simulation. AIAA Scitech 2019 Forum, 07-11 Jan 2019, San Diego, USA. DOI: 10.2514/6.2019-0317

The roadmap laid out in the CFD Vision 2030 document [1] suggests that a decision to move away from RANS research needs to be made in the current timeframe (around 2020). This paper outlines industry requirements for improved predictions of turbulent flows and the cost-barrier that is often associated with reliance on scale resolving methods. Capabilities of RANS model accuracy for simple and complex flow fields are assessed, and modeling practices that degrade predictive accuracy are identified. Suggested research topics are identified that have the potential to improve the applicability and accuracy of RANS models. We conclude that it is important that some part of a balanced turbulence modeling research portfolio should include RANS efforts.
