  • Interaction between the Blasius boundary layer and a free surface 

    Tsang, Jonathan; Dalziel, Stuart Bruce; Vriend, Nathalie Maria (Cambridge University PressJournal of Fluid Mechanics, 2018-03-25)
    We consider the steady, supercritical flow of a fluid layer. The layer is bounded above by a free surface and below by a rigid no-slip base. The base is in two parts: the downstream part of the base is stationary, while ...

  • Linear and nonlinear wave propagation in booming sand dunes 

    Vriend, Nathalie Maria; Hunt, ML; Clayton, RW (AIPPhysics of Fluids, 2015-10-27)
    The current field study examines linear and non-linear acoustic waves found in large desert sand dunes using field measurements of wave speed, frequency content, dispersion, and polarization. At the dune fields visited, ...

  • Size segregation in a granular bore 

    Edwards, AN; Vriend, Nathalie Maria (American Physical SocietyPhysical Review Fluids, 2016-10-06)
    We investigate the effect of particle-size segregation in an upslope propagating granular bore. A bidisperse mixture of particles, initially normally graded, flows down an inclined chute and impacts with a closed end. This ...
