  • On turbulent particle fountains 

    Mingotti, Nicola; Woods, Andrew W. (Cambridge University Press, 2016-03-23)
    We describe new experiments in which particle-laden turbulent fountains with source Froude numbers 20 > Fr₀ > 6 are produced when particle-laden fresh water is injected upwards into a reservoir filled with fresh water. We ...
  • On the transport of heavy particles through a downward displacement-ventilated space 

    Mingotti, Nicola; Woods, Andrew W. (Cambridge University Press, 2015-06-05)
    We investigate the transport of relatively heavy, small particles through a downward displacement-ventilated space. A flux of particles is supplied to the space from a localised source at a high level and forms a turbulent ...
  • On the transport of heavy particles through an upward displacement-ventilated space 

    Mingotti, Nicola; Woods, Andrew W. (CUP, 2015-05-07)
    We explore the transport of heavy particles through an upward displacement-ventilated space. The space incorporates a localised source of buoyancy which generates a turbulent buoyant plume. The plume uid is contaminated ...
  • Buoyancy driven dispersion in a layered porous rock 

    Farcas, Adrian; Woods, Andrew W. (CUP, 2015-02-12)
    We investigate the longitudinal dispersion of a passive tracer by a gravity-driven flow in a porous medium consisting of a series of independent horizontal layers connected to a constant pressure source. We show that in a ...
