      Dispersed-phase structural anisotropy in homogeneous magnetohydrodynamic turbulence at low magnetic Reynolds number 

      Rouson, D. I.; Kassinos, Stavros C.; Moulitsas, I.; Sarris, I. E.; Xu, X. (2008)
      A new tensor statistic, the dispersed-phase structure dimensionality Dp, is defined to describe the preferred orientation of clusters of discrete bodies. The evolution of Dp is calculated via direct numerical simulations ...

      Structure anisotropy in MHD turbulence subjected to mean shear and frame rotation 

      Kassinos, Stavros C.; Wray, A. (Affiliation: Dept. of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, CyprusAffiliation: Department of Mechanical Engineering, Stanford University, Stanford, CA 94305, United StatesAffiliation: Center for Turbulence Research, NASA Ames Research Center, United StatesCorrespondence Address: Kassinos, S.C.Dept. of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, Cyprusemail: kassinos@ucy.ac.cy, 2005)
      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 ...
