  • Advanced fluid modelling of transport in tokamaks 
    Weiland, J. (Вопросы атомной науки и техники, 2002)
    The need for and conditions for fluid modelling of tokamak transport is discussed. In particular emphasis is put on fluid closure, off diagonal transport fluxes and non- Markovian effects. Some recent results of a fluid ...
  • Non-Markovian effects in turbulent diffusion: kinetic theory and numerical simulation 
    Zagorodny, A.G.; Zasenko, V.I.; Weiland, J.; Holod, I. (Вопросы атомной науки и техники, 2002)
    The theory of time-nonlocal random processes formulated in terms of non-Markovian Fokker-Planck equation is used to describe the results of numerical simulations of particle diffusion in the random longitudinal field with ...
  • Non-Markovian Fokker-Planck equations and turbulent diffusion in plasmas 
    Zagorodny, A.; Weiland, J. (Condensed Matter Physics, 1998)
    Non-Markovian generalization of the Fokker-Planck equation is proposed in attempt to describe the influence of memory effects on stochastic particle motion in both velocity and configuration spaces. General relations between ...
  • Non-Markovian renormalization of kinetic coefficients for drift wave turbulence 
    Zagorodny, A.; Weiland, J. (Condensed Matter Physics, 2001)
    Statistical theory of non-Markovian effects in turbulent transport is applied to the description of plasma turbulence in a magnetoactive plasma in the drift-kinetic approximation. Renormalized transition probability is ...
