    • Resistive magnetohydrodynamic reconnection : resolving long-term, chaotic dynamics 

      Keppens, R.; Porth, O.; Galsgaard, K.; Frederiksen, J.T.; Restante, A.L.; Lapenta, G.; Parnell, C. (2013-09-13) - Journal article
      In this paper, we address the long-term evolution of an idealised double current system entering reconnection regimes where chaotic behavior plays a prominent role. Our aim is to quantify the energetics in high magnetic ...

    • The effect of slip length on vortex rebound from a rigid boundary 

      Sutherland, D.; Macaskill, C.; Dritschel, D.G. (2013-09-23) - Journal article
      The problem of a dipole incident normally on a rigid boundary, for moderate to large Reynolds numbers, has recently been treated numerically using a volume penalisation method by Nguyen van yen, Farge, and Schneider [Phys. ...

    • Shallow-water vortex equilibria and their stability 

      Płotka, H.; Dritschel, D.G. (2011-01-01) - Journal article
      We first describe the equilibrium form and stability of steadily-rotating simply-connected vortex patches in the single-layer quasi-geostrophic model of geophysical fluid dynamics. This model, valid for rotating shallow-water ...

    • Boundary layer flow beneath an internal solitary wave of elevation 

      Carr, Magda; Davies, P A (2010-02) - Journal article
      The wave-induced flow over a fixed bottom boundary beneath an internal solitary wave of elevation propagating in an unsheared, two-layer, stably stratified fluid is investigated experimentally. Measurements of the velocity ...

    • An analytical, phenomenological and numerical study of geophysical and magnetohydrodynamic turbulence in two dimensions 

      Blackbourn, Luke A. K. (University of St Andrews, 2013-11-29) - Thesis
      In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes ...
