On a Fractal Model for Turbulence
Zeitschrift für Naturforschung A, 1993 Abstract An interpretation of a recently proposed generic model for fractal basin boundaries in terms of a cascade-like model for turbulence is presented. Intermittency effects are shown by the analysis of structure functions and non-Gaussian probability density functions.

Modeling Turbulent Flow in Stirred Tanks with CFD: The Influence of the Modeling Approach, Turbulence Model and Numerical Scheme [PDF]
, 2004 Single phase turbulent flow in a tank stirred by a down- and an up-pumping pitched blade turbine has been simulated using CFD. The effect of the modeling approach, discretization scheme and turbulence model on mean velocities, turbulent kinetic energy ...

Turbulence transport throughout the heliosphere [PDF]
, 2007 We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

Differentiable physics-enabled closure modeling for Burgers’ turbulence
Machine Learning: Science and Technology, 2023 Data-driven turbulence modeling is experiencing a surge in interest following algorithmic and hardware developments in the data sciences. We discuss an approach using the differentiable physics paradigm that combines known physics with machine learning ...
