Christina Lienstromberg, Stefan Schiffer, Richard Schubert. Data from experiments and direct simulations of turbulence have historically been used to calibrate simple engineering models such as those based on the Reynolds-averaged NavierStokes (RANS) equations. This work proves that data-driven discovery combined with molecular simulations is a promising and alternative method to derive governing equations in fluid dynamics, and it is expected to pave a new way to establish the governing equations of non-equilibrium flows and complex fluids. In lack of a full physical description, existing database and experimental data will be used to develop hybrid predictive tools, which will be physics-based and data-driven. Brunton, Proctor, Kutz.

Fluid turbulence was identified in 1949 by Von Neumann, one of the founders of modern computers, as one of the remaining grand challenges in physics. The alternative to a mechanism based approach is a data-driven one, which in the past was reduced to either fitting data with trial functions, multivariate of linear combinations of hand-selected functions or linear decomposition techniques like principal component analysis, which in mechanics is known as proper orthogonal decomposition.
