    • Robustness of predator-prey models for confinement regime transitions in fusion plasmas 

      Zhu, H; Chapman, Sandra; Dendy, R.O. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Energy transport and confinement in tokamak fusion plasmas is usually determined by the coupled nonlinear interactions of small-scale drift turbulence and larger scale coherent nonlinear structures, such as zonal flows, together with free energy sources such as temperature gradients. Zero-dimensional models, designed to embody plausible physical narratives for these interactions, can help to ...

    • Wavelet determination of magnetohydrodynamic-range power spectral exponents in solar wind turbulence seen by Parker Solar Probe 

      Wang, X.; Chapman, Sandra; Dendy, R.O.; Hnat, B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-20)
      Context. The high Reynolds number solar wind flow provides a natural laboratory for the study of turbulence in situ. Parker Solar Probe samples the solar wind between 0.17 AU and 1 AU, providing an opportunity to study how turbulence evolves in the expanding solar wind.<p> <p>Aims. We aim to obtain estimates of the scaling exponents and scale breaks of the power spectra of magnetohydrodynamic ...
