Astrophysical turbulence modeling [PDF]

Reports on Progress in Physics, 2011
The role of turbulence in various astrophysical settings is reviewed. Among the differences to laboratory and atmospheric turbulence we highlight the ubiquitous presence of magnetic fields that are generally produced and maintained by dynamo action.

Turbulence models [PDF]

The subject of modeling turbulence for use with the JAWS wind shear data sets is addressed. The present FAA AC 120-41 wind shear models are quasisteady wind models. FAA recommends superimposing upon these winds a Dryden spectrum model of turbulence.

Effects of side orifice dimensions on characteristics of flow field in rectangular channels [PDF]

Journal of Applied Research in Water and Wastewater, 2022
In this paper, the flow in the vicinity of rectangular side orifices placed in main channels is estimated by means of the FLOW-3D model. To reconstruct the flow free surface, the volume of fluid (VOF) approach is utilized.

Burgers' Turbulence Models [PDF]

The Physics of Fluids, 1969
A detailed investigation of the stability of the solutions and the growth of secondary solutions beyond the critical points is carried out for the Burgers' model equations. It is found that the transitions at some critical points are very much like the intuitive description given by Landau; however, the possibility of finite jumps is also encountered.
