      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 ...

      Large-eddy simulations of unidirectional water flow over dunes 

      Grigoriadis, D. G. E.; Balaras, E.; Dimas, A. A. (2009)
      The unidirectional, subcritical flow over fixed dunes is studied numerically using large-eddy simulation, while the immersed boundary method is implemented to incorporate the bed geometry. Results are presented for a typical ...

      One-point modelling of rapidly deformed homogeneous turbulence 

      Reynolds, W. C.; Kassinos, Stavros C. (1995)
      Turbulent stresses introduced by Osborne Reynolds do not, by themselves, provide an adequate tensorial base for one-point modelling of rapidly distorted turbulence because they do not carry critical information about the ...

      One-point turbulence structure tensors 

      Kassinos, Stavros C.; Reynolds, W. C.; Rogers, M. M. (2001)
      The dynamics of the evolution of turbulence statistics depend on the structure of the turbulence. For example, wavenumber anisotropy in homogeneous turbulence is known to affect both the interaction between large and small ...

      Structure-based turbulence model: Application to a rotating pipe flow 

      Poroseva, S. V.; Kassinos, Stavros C.; Langer, C. A.; Reynolds, W. C. (2002)
      A new approach for modeling the one-point turbulence statistics, which takes into account the information on turbulence structure, has been suggested in Kassinos and Reynolds (Report TF-61, Thermosciences Division, Department ...

      Structure-based turbulence modeling for wall-bounded flows 

      Kassinos, Stavros C.; Langer, C. A.; Haire, S. L.; Reynolds, W. C. (2000)
      The performance of Reynolds stress transport (RST) models in non-equilibrium flows is limited by the lack of information about two dynamically important effects: The role of energy-containing turbulence structure ...
