Parabolic turbulence k-epsilon model with applications in fluid flows through permeable media [PDF]

Opuscula Mathematica
In this work, we study a one-equation turbulence \(k\)-epsilon model that governs fluid flows through permeable media. The model problem under consideration here is derived from the incompressible Navier-Stokes equations by the application of a time ...

COMPARISON OF STANDARD k-epsilon AND SST k-omega TURBULENCE MODEL FOR BREASTSHOT WATERWHEEL SIMULATION

, 2020
Currently, Computational Fluid Dynamics (CFD) was utilized to predict the performance, geometry optimization or physical phenomena of a breastshot waterwheel. The CFD method requires the turbulent model to predict the turbulent flow.

Renormalization Group Analysis of k-.EPSILON. Model and LES Model on Turbulence Problem.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991
This paper presents the renormalization group analysis for the turbulence problem. This procedure does not require any experimentally adjustable parameters. The following numerical values for important constants of turbulent flows can be derived : for instance, the Kolmogorov constant for the inertial-range spectrum Ck=1.605 ; turbulent Prandtl number ...

The turbulence scales of a wind turbine wake: A revisit of extended k-epsilon models

Journal of Physics: Conference Series, 2018
The turbulence time and length scales of a single wind turbine wake subjected to atmospheric turbulence are calculated from two large eddy simulations that differ in ambient turbulence intensity. The smallest turbulence length scale in the wake is about half the rotor radius and it increases for higher ambient turbulence levels.

A K-Epsilon RANS turbulence model for incompressible MHD flow at high Hartmann number in fusion liquid metal blankets

, 2017
As fusion liquid metal blankets work under strong magnetic fields, the liquid metal would form magnetohydrodynamics (MHD) flow of high Hartmann number in ducts. With the anisotropic suppression effect of magnetic field towards turbulence fluctuation, MHD
