Statistical measures of structural anisotropy in MHD turbulence subjected to mean shear and frame rotation
(2006)
We consider homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field while being sheared in fixed and rotating frames. We take both the frame-rotation axis and the applied magnetic ...
Representing anisotropy of two-point second-order turbulence velocity correlations using structure tensors
(2008)
A locally homogeneous representation for the two-point, second-order turbulent velocity fluctuation Rij(x,r) = 〈u′i(x)u′i(x+r)〉 is formulated in terms of three linearly independent structure tensors [Kassinos et al., J. ...
A simplified structure-based model using standard turbulence scale equations: computation of rotating wall-bounded flows
(2006)
Two linear eddy-viscosity models, the v2-f and k-ω models, have been combined with an algebraic structure-based algorithm for the evaluation of the Reynolds stresses. This closure was originally designed as an integral ...
