  • Completeness, conservation and error in SPH for fluids

    Vaughan, G.L.; Healy, Terry R.; Bryan, Karin R.; Sneyd, Alfred D.; Gorman, R.M. (John Wiley & Sons, Ltd., 2008)
    Smoothed particle hydrodynamics (SPH) is becoming increasingly common in the numerical simulation of complex fluid flows and an understanding of the errors is necessary. Recent advances have established techniques for ...
  • Instability of a plane conducting free surface submitted to an alternating magnetic field

    Fautrelle, Y.; Sneyd, Alfred D. (1998)
    This paper considers the stability of a horizontal liquid-metal free surface in the presence of a horizontal alternating magnetic field. A weak formulation is used to derive a generalized Mathieu–Hill equation for the ...
  • Magnetic flux braiding: Force-free equilibria and current sheets

    Longbottom, A.W.; Rickard, G.J.; Craig, Ian J.D.; Sneyd, Alfred D. (1998-06)
    We use a numerical, nonlinear, multigrid magnetic relaxation technique to investigate the generation of current sheets in three-dimensional magnetic flux braiding experiments. We are able to catalog the relaxed nonlinear ...
  • Nonlinear development of the kink instability in coronal flux tubes

    Craig, Ian J.D.; Sneyd, Alfred D. (1990)
    Solar prominences and flares are believed to be caused by rapid release of magnetic energy stored in coronal magnetic fields. Recent studies of the linear phase of ideal MHD instabilities has shown that energy release is ...
  • The response of a floating ice sheet to an accelerating line load

    Miles, J.; Sneyd, Alfred D. (Cambridge University Press, 2003)
    The two-dimensional response of a thin, floating sheet of ice to a line load that accelerates from rest at $t = 0$ to a uniform velocity V for $t \geq T$ is determined through an integral-transform solution of the linearized ...

  • Coronal magnetic energy release by current sheet reconnection

    Heerikhuisen, J. (The University of Waikato, 2001)
    In this thesis we investigate the rapid release of energy in the solar corona, with a particular view to understanding the solar flare in which magnetic reconnection is thought to play a key role. A review of existing ...
  • Current sheet formation in uniformly twisted magnetic flux tubes

    Ali, Farhad (The University of Waikato, 2001)
    A viable mechanism for coronal heating is conversion of magnetic field energy into heat through magnetic reconnection in current sheets. Two processes capable of generating current sheets in the solar corona are studied ...
  • Electromagnetic stirring using a travelling magnetic field

    Saad, Mohd. Noor Bin (The University of Waikato, 2004)
    Electromagnetic stirring of liquid metal is widely used during continuous casting in iron and steel industries to improve the quality of the products. In this thesis we aim to develop a theory for traveling linear stirrers ...
  • Aerodynamics of two-dimensional sail wings

    Bundock, Michael Stephen (The University of Waikato, 1980)
    The purpose of this work is to obtain the exact solution for the profile and characteristics of a two-dimensional sail, immersed in an inviscid incompressible fluid. An experimental investigation was also performed and ...
  • Reduction of water and bed levels in the lower Waikato River

    Wo, You Gu (University of Waikato, 1994)
    The major aims of this thesis are to determine the historical qualitative and quantitative reduction in water and bed levels of the lower Waikato River, to identify probable factors influencing the reduction, and to predict ...
