  • Ward, Jonathan A; Fowler, Andrew C. (SpringerOpen, 2016)
    Purpose: The polishing of cut lead glass crystal is effected through the dowsing of the glass in a mixture of two separate acids, which between them etch the surface and as a result cause it to be become smooth. In order ...
  • Fannon, James S.; Moyles, Iain R.; Fowler, Andrew C. (Cambridge University Press, 2019)
    We consider the instability properties of dense granular flow in inclined plane and plane shear geometries as tests for the compressible inertial-dependent rheology. The model, which is a recent generalisation of the ...
  • Lee, William T.; Fowler, Andrew C.; Power, O.; Healy, S.; Browne, J. (American Institute of Physics, 2010)
    Polycrystalline silicon fuses are one time programmable memory elements which allow the calibration of integrated circuits at wafer and package level. We present a zero-dimensional lumped parameter model of the programming ...
  • Livingstone, Stephen J.; Utting, Daniel J.; Ruffell, Alastair; Clark, Chris D.; Pawley, Steven; Atkinson, Nigel; Fowler, Andrew C. (Nature Publishing Group, 2016)
    Recent proxy measurements reveal that subglacial lakes beneath modern ice sheets periodically store and release large volumes of water, providing an important but poorly understood influence on contemporary ice dynamics ...
  • Fowler, Andrew C.; Kopteva, Natalia; Oakley, Charles (Society for Industrial and Applied Mathematics, 2006)
    We consider a deterministic model of landscape evolution through the mechanism of overland flow over an erodible substrate, using the St. Venant equations of hydraulics together with the Exner equation for hillslope erosion. ...
  • Benn, D. I.; Fowler, Andrew C.; Hewitt, I.; Sevestre, H. (Cambridge University Press, 2019)
    We present the first general theory of glacier surging that includes both temperate and polythermal glacier surges, based on coupled mass and enthalpy budgets. Enthalpy (in the form of thermal energy and water) is gained ...
  • Zammett, R.J; Fowler, Andrew C. (Society for Industrial and Applied Mathematics, 2010)
    Spiral-shaped canyons on the polar ice caps of Mars are striking morphological features whose explanation is still mysterious. We pose a model for the kinetics at the ice-atmosphere interface based on the positive feedback ...
  • Fannon, James S.; Fowler, Andrew C.; Moyles, Iain R. (The Royal Society Publishing, 2017)
    We summarize the present form of the instability theory for drumlin formation, which describes the coupled subglacial flow of ice, water and sediment. This model has evolved over the last 20 years, and is now at the point ...
  • Khaleque, Tania S; Fowler, Andrew C.; Howell, P D; Vynnycky, Michael (American Institute of Physics, 2015)
    Motivated by convection of planetary mantles, we consider a mathematical model for Rayleigh-Benard convection in a basally heated layer of a fluid whose viscosity depends strongly on temperature and pressure, defined in ...
  • Fowler, Andrew C. (Springer, 2019)
    In this paper we revisit the problem of explaining phase transition by a study of a form of the Boltzmann equation, where inter-molecular attraction is included by means of a Vlasov term in the evolution equation for the ...
  • Moyles, Iain R.; Fowler, Andrew C. (Springer, 2018)
    Nitrification at the site of a contaminant ammonium plume from a former coal carbonisation plant can be modelled with three competing bacterial populations of Nitrosomonas, Nitrobacter, and Brocadia anammoxidans. Oscillations ...
  • Cribbin, Laura B. (University of Limerick, 2013)
    Under the influence of regional groundwater ow, pollution in an aquifer can migrate to streams or wells. This can have catastrophic consequences for human health and local ecosystems. Fortunately, there is a suite of ...
  • Kyrke-Smith, T.M.; Katz, R.F; Fowler, Andrew C. (International Glaciological Society, 2013)
    One challenge in improving our understanding of ice-stream dynamics is to develop models of the spatial and temporal transition from ice-sheet to ice-stream flow. We address this with a new, vertically integrated, higher-order ...
  • Kyrke-Smith, T.M.; Katz, R.F; Fowler, Andrew C. (American Geophysical Union, 2015)
    Observations have long associated ice streams with the presence of meltwater at the bed. More recently, theoretical models have been able to reproduce ice stream behavior as a consequence of the coupled dynamics of ice and ...
  • Kyrke-Smith, T.M.; Fowler, Andrew C. (2014)
    The existence of both water and sediment at the bed of ice streams is well documented, but there is a lack of fundamental understanding about the mechanisms of ice, water and sediment interaction. We pose a model to describe ...
  • Robinson, Marguerite; Fowler, Andrew C.; Alexander, A.J.; O'Brien, Stephen B.G. (American Institute of Physics, 2008)
    We describe a simple model of a bubbly two-phase flow which is able to explain why waves propagate downward when a pint of Guinness is poured, and also how the waves are generated. Our theory involves a physically based ...
