  • Dissipative structures in a nonlinear dynamo 

    Gilbert, Andrew D.; Ponty, Y.; Zheligovsky, V. (Taylor & Francis, 2010-12-02)
    This paper considers magnetic field generation by a fluid flow in a system referred to as the Archontis dynamo: a steady nonlinear magnetohydrodynamic (MHD) state is driven by a prescribed body force. The field and flow become ...
  • Kinematic dynamo action in large magnetic Reynolds number flows driven by shear and convection 

    Ponty, Y.; Gilbert, Andrew D.; Soward, Andrew M. (Cambridge University Press, 2001)
    A numerical investigation is presented of kinematic dynamo action in a dynamically driven fluid flow. The model isolates basic dynamo processes relevant to field generation in the Solar tachocline. The horizontal plane ...
  • The onset of thermal convection in Ekman–Couette shear flow with oblique rotation 

    Ponty, Y.; Gilbert, Andrew D.; Soward, Andrew M. (Cambridge University Press, 2003)
    The onset of convection of a Boussinesq fluid in a horizontal plane layer is studied. The system rotates with constant angular velocity Ω, which is inclined at an angle ϑ to the vertical. The layer is sheared by keeping ...
