Self-consistent modeling of turbulence and transport

Journal of Computational Physics, 2003
The authors describe a method of coupling transport and turbulence, which they illustrate with an application to two-dimensional Hasegawa-Wakatani model equations for plasma turbulence. The authors augment the basic scheme with two methods, equally successful, for dealing with locally antidiffusive behaviour.

MODELING OF TURBULENT TRANSPORT IN LASER SURFACE ALLOYING

Numerical Heat Transfer, Part A: Applications, 2003
In this paper, we present a modified k-ε model capable of addressing turbulent molten metal-pool convection in the presence of a continuously evolving phase-change interface during a laser surface alloying process. The phase change aspects of the present problem are addressed using a modified enthalpy-porosity technique.

MODELING AND CALCULATION OF TURBULENT TRANSPORT IN FREE-SHEAR FLOWS

Numerical Heat Transfer, 1987
The applicability of the combined bulk convection and gradient transport hypotheses for modeling turbulent diffusion is investigated. The resulting model equation, namely the one-equation model, is solved for free-shear flows by an implicit finite-difference method.

Turbulence scaling laws and transport models

AIP Conference Proceedings, 2008
This paper presents some elementary results concerning the dimensionless scaling laws of turbulent transport in fusion plasmas and the way they provide constraints on transport models.

Modeling Turbulent Transport in Stratified Estuary

Journal of Hydraulic Engineering, 1988
A finite difference mathematical model for the calculation of estuarine flow and transport processes is presented. Due to the emphasis on engineering applications, turbulence closure is formulated on the basis of mixing length and damping functions.

Solar Wind Modeling With Turbulence Transport and Heating

Astrophysical Journal, 2011
We have developed an axisymmetric steady-state solar wind model that describes properties of the large-scale solar wind, interplanetary magnetic field, and turbulence throughout the heliosphere from 0.3 AU to 100 AU. The model is based on numerical solutions of large-scale Reynolds-averaged magnetohydrodynamic equations coupled with a set of small ...

Modeling of Cloud Scale Turbulent Transport

1997
Abstract : Our long term goals are to understand the dynamics of atmospheric motions on scales of 10 kilometers and less in sufficient detail to be able to provide a consistent subgrid scale turbulent closure for models across a range of scales, and to be able to utilize simulated variances as a measure of forecast ...
