Multi-scale Correlation Functions in Strong Turbulence
, 1999 Under the framework of V. Yakhot [Phys.Rev.E, {\bf57}, 1737 (1998)] modelling of intermittent structure functions in fully developed turbulence and based on the experimentally supported Markovian nature of turbulence cascades [R.Friedrich and J.Peinke ...

Modelling the Interfacial Flow of Two Immiscible Liquids in Mixing Processes [PDF]
, 2005 This paper presents an interface tracking method for modelling the flow of immiscible metallic liquids in mixing processes. The methodology can provide an insight into mixing processes for studying the fundamental morphology development mechanisms for ...

Explosive Turbulent Magnetic Reconnection [PDF]
, 2013 We report simulation results for turbulent magnetic reconnection obtained using a newly developed Reynolds-averaged magnetohydrodynamics model. We find that the initial Harris current sheet develops in three ways, depending on the strength of turbulence: laminar reconnection, turbulent reconnection, and turbulent diffusion.

A Dynamic Mixed Model for General Circulation Models
Meteorologische Zeitschrift, 2023 An extension of the dynamic Smgarorinsky model (DSM) is presented. In the so-called dynamic mixed model (DMM), the Leonard stress (i.e., the resolved part of the Reynolds stress) is no longer parameterized in the test filter range by the Smagorinsky ...

Qian Jian and His Contribution to Small-Scale Turbulence Studies [PDF]
, 2021 Qian Jian, a Chinese theoretical physicist and fluid dynamicist, devoted the second part of his scientific life to the physical understanding of small-scale turbulence to the exclusion of all else. Qian developed his own statistical theory of small-scale turbulence, based on the Liouville (1853) equation and a perturbation variational approach to non ...

A SHELL MODEL TURBULENT DYNAMO [PDF]
The Astrophysical Journal, 2011 Turbulent dynamo phenomena, observed almost everywhere in astrophysical objects and also in the laboratory in the recent VKS2 experiment, are investigated using a shell model technique to describe magnetohydrodynamic turbulence. Detailed numerical simulations at very high Rossby numbers (α2 dynamo) show that as the magnetic Reynolds number increases ...

Adaptively refined large eddy simulations of clusters
, 2009 We present a numerical scheme for modelling unresolved turbulence in cosmological adaptive mesh refinement codes. As a first application, we study the evolution of turbulence in the intra-cluster medium and in the core of a galaxy cluster.
