          6. The mission and requirements of a turbulence model

          Abstract:

          The purpose of the talk is a comprehensive discussion of the features a turbulence model proposed for Reynolds-Averaged Navier-Stokes (RANS) CFD must or preferably should possess, first in order to be properly implemented numerically, and second to be relatively accurate in a wide range of applications, and become widely used.

          The need for this discussion is reinforced by the current wave of Artificial Intelligence and Machine Learning (ML) proposals, which brings into the field researchers with little “turbulence culture” (the subset of turbulence modeling culture is itself even more confusing).

          It is all too easy to conduct a “successful” ML project that gives an object that is, simply, not a turbulence model. Although a universal model will obviously never be created, it is argued that specialized models are undesirable, considering that models are expected to function well with a single formulation in all regions
