  • Bush, John W. M. (Les Editions de l’Ecole Polytechnique, 2013)
    We consider the aerodynamics of football, specifically, the interaction between a ball in flight and the ambient air. Doing so allows one to account for the characteristic range and trajectories of balls in flight, as well ...
  • Burton, Lisa Janelle; Bush, John W. M. (American Institute of Physics, 2012-10)
    We consider the role of flexibility in the weight-bearing characteristics of bodies floating at an interface. Specifically, we develop a theoretical model for a two-dimensional thin floating plate that yields the maximum ...
  • Jung, Sunghwan; Reis, Pedro Miguel; James, Jillian; Clanet, Christophe; Bush, John W. M. (American Institute of Physics, 2009-09)
    Capillary forces dominate gravity on a small scale and may deform flexible bodies in both natural and laboratory settings. Two examples are considered here: floating flowers and spider webs.
  • Bush, John W. M. (American Physical Society, 2009-01)
    We examine the complex dynamics arising when a water droplet bounces on a horizontal soap film suspended on a vertically oscillating circular frame. A variety of simple and complex periodic bouncing states are observed, ...
  • Gilet, Tristan; Bush, John W. M. (American Institute of Physics (AIP), 2012-12)
    We present the results of an experimental investigation of fluid drops impacting an inclined rigid surface covered with a thin layer of high viscosity fluid. We deduce the conditions under which droplet bouncing, splitting, ...
  • Renvoise, P.; Bush, John W. M.; Prakash, Manu; Quere, D. (European Physical Society by EDP Sciences, IOP Publishing and Società Italiana di Fisica, 2009-07)
    We present the results of a combined experimental and theoretical investigation of the motion of wetting droplets in tapered capillary tubes. We demonstrate that drops may move spontaneously towards the tapered end owing ...
  • Bush, John W. M.; Molacek, Jan (Cambridge University Press, 2013-06)
    We present the results of a combined experimental and theoretical investigation of millimetric droplets bouncing on a vertically vibrating fluid bath. We first characterize the system experimentally, deducing the dependence ...
  • Bush, John W. M.; Molacek, Jan (Cambridge University Press, 2013-06)
    We present the results of a combined experimental and theoretical investigation of droplets walking on a vertically vibrating fluid bath. Several walking states are reported, including pure resonant walkers that bounce ...
  • Harris, Daniel Martin; Molacek, Jan; Bush, John W. M.; Wind-Willassen, Oistein (American Institute of Physics (AIP), 2013-08)
    We present the results of an integrated experimental and theoretical investigation of droplets bouncing on a vibrating fluid bath. A comprehensive series of experiments provides the most detailed characterisation to date ...
  • Gilet, Tristan; Bush, John W. M. (Cambridge University Press, 2009-04)
    We present the results of a combined experimental and theoretical investigation of droplets falling onto a horizontal soap film. Both static and vertically vibrated soap films are considered. In the static case, a variety ...
  • Bush, John W. M. (American Meteorological Society, 2009-04)
    A cold event at around 8200 calendar years BP and the release, at around that time, of a huge freshwater outburst from ice-dammed glacial Lake Agassiz have lent support to the idea that the flood triggered the cold event. ...
  • Reis, Pedro Miguel; Hure, Jeremy; Jung, Sungwan; Bush, John W. M.; Clanet, Christophe (Royal Society of Chemistry, The, 2010-10)
    We introduce a novel technique for grabbing water with a flexible solid. This new passive pipetting mechanism was inspired by floating flowers and relies purely on the coupling of the elasticity of thin plates and the ...
  • Labousse, M.; Bush, John W. M. (American Institute of Physics (AIP), 2013-09)
    When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact, provided a critical flow rate is exceeded. We here examine a phenomenon that arises below this jump ...
  • Bush, John W. M.; Hu, David L. (Cambridge University Press, 2010-02)
    We present the results of a combined experimental and theoretical investigation of the dynamics of water-walking insects and spiders. Using high-speed videography, we describe their numerous gaits, some analogous to those ...
  • Bush, John W. M.; Messio, Laura; Blanchette, Francois (American Institute of Physics, 2009-07)
    We present the results of a combined experimental and numerical investigation of the coalescence of a drop with a liquid reservoir of a miscible but distinct fluid. Particular attention is given to elucidating the influence ...
  • Prakash, Manu; Bush, John W. M. (Elsevier, 2010-12)
    The rough integument of water-walking arthropods is well-known to be responsible for their water-repellency [1], [2], [3] and [4]; however, water-repellent surfaces generally experience reduced traction at an air–water ...
  • Kim, Wonjung; Bush, John W. M. (Cambridge University Press, 2012-04)
    We examine the fluid mechanics of drinking in nature. We classify the drinking strategies of a broad range of creatures according to the principal forces involved, and present physical pictures for each style. Simple scaling ...
  • Kim, Wonjung; Gilet, Tristan; Bush, John W. M. (National Academy of Sciences, 2011-10)
    Nectar drinkers must feed quickly and efficiently due to the threat of predation. While the sweetest nectar offers the greatest energetic rewards, the sharp increase of viscosity with sugar concentration makes it the most ...
  • Kim, Wonjung; Bush, John W. M.; Jensen, Kaare H.; Holbrook, N. Michele (Royal Society, 2013-04)
    Many biological and man-made systems rely on transport systems for the distribution of material, for example matter and energy. Material transfer in these systems is determined by the flow rate and the concentration of ...
  • Harris, Daniel Martin; Bush, John W. M. (American Institute of Physics (AIP), 2013-09)
    A millimetric droplet can be induced to bounce on the surface of a fluid bath by vibrating the bath near the droplet's resonant frequency (Figure 1(a) ). [superscript 1–3] The localized field of Faraday waves excited by ...
