So does water, in some cases: Around a small model of a rock - and - concrete dike, for instance, water may display a so - called laminar flow pattern, whereas in the real world it displays more chaotic turbulent flows.

The Southampton research team, led by Richard Sandberg, Professor of Fluid Dynamics and Aeroacoustics, and including Dr Andrew Wheeler and Professor Neil Sandham, has identified that Direct Numerical Simulations (DNS), a model - free approach based on first principles (no assumptions or modelling are used) can help to develop an improved understanding of the role of turbulent phenomena in the flow - field and determine the validity of current turbulence modelling.

They have developed a simple mathematical model that has helped them show how turbulent flows will evolve over intervals.

From blood flow to weather patterns, the equations prove invaluable in modeling turbulent environments; even so, physically meaningful solutions are nearly impossible to come by.

They then applied models of holographic duality to translate the black hole's physics to the turbulent flows of superfluids.

The team directly measured terms in turbulence model equations, providing insights into the global nature of the mixing (e.g., faster mixing near the edges of the turbulent fluid layer when compared with the core) and identifying the dominant mechanisms governing the flow evolution.

O'Gorman, P. A., and T. Schneider, 2006: Stochastic models for the kinematics of moisture flux and condensation in homogeneous turbulent flows.

As far as I know there is no satisfactory CFD model to simulate the regime where laminar flow changes to turbulent flow.

b) provide a scaling argument comparing the «turbulent viscosity» used in the model to the magnitude one might expect in a real flow.

That is how much energy is exchanged by turbulent flows which are two small for the model to capture?
