      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 ...

      Dispersed-phase structure in sheared MHD turbulence 

      Xu, X.; Rouson, D. W. I.; Kassinos, Stavros C.; Radhakrishnan, H. (2012)
      Direct numerical simulations are performed to examine particle dispersion in homogeneous turbulence subjected to mean shear and an externally applied magnetic field. We employ the Brucker et al. algorithm for simulating ...

      A grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003 

      Rouson, D. W. I.; Rosenberg, R.; Xu, X.; Moulitsas, I.; Kassinos, Stavros C. (2008)
      Computational complexity theory inspires a grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003. A novel complexity analysis estimates that structured programming time grows at least quadratically with ...
