    • Confined rotating convection with large Prandtl number: centrifugal effects on wall modes 

      Curbelo Hernández, Jezabel; López Moscat, Juan Manuel; Mancho Sánchez, Ana María; Marqués Truyol, Francisco (2014-01-23)
      Article
      Open Access
      Thermal convection in a rotating cylinder with a radius-to-height aspect ratio of G=4 for fluids with large Prandtl number is studied numerically. Centrifugal buoyancy effects are investigated in a regime where the Coriolis ...

    • Inertial waves in rapidly rotating flows: a dynamical systems perspective 

      López Moscat, Juan Manuel; Marqués Truyol, Francisco (2016-11-02)
      Article
      Open Access
      An overview of recent developments in a wide variety of enclosed rapidly rotating flows is presented. Highlighted is the interplay between inertial waves, which have been predicted from linear inviscid considerations, and ...

    • Instability of plumes driven by localized heating 

      López Moscat, Juan Manuel; Marqués Truyol, Francisco (2013-12)
      Article
      Open Access
      Plumes due to localized buoyancy sources are of wide interest owing to their prevalence in many situations. This study investigates the transition from laminar to turbulent dynamics. Several experiments have reported that ...

    • Precession of a rapidly rotating cylinder flow: traverse through resonance 

      Marqués Truyol, Francisco; López Moscat, Juan Manuel (2015-10-06)
      Article
      Restricted access - publisher's policy
      Recent experiments using a rapidly rotating and precessing cylinder have shown that for specific values of the precession rate, aspect ratio and tilt angle, sudden catastrophic transitions to turbulence occur. Even if the ...

    • Rapidly rotating cylinder flow with an oscillating sidewall 

      López Moscat, Juan Manuel; Marqués Truyol, Francisco (2014-02-17)
      Article
      Open Access
      We present numerical simulations of a flow in a rapidly rotating cylinder subjected to a time-periodic forcing via axial oscillations of the sidewall. When the axial oscillation frequency is less than twice the rotation ...

    • Small aspect ratio Taylor-Couette flow: onset of a very-low-frequency three-torus state 

      López Moscat, Juan Manuel; Marqués Truyol, Francisco (2003-09-03)
      Article
      Open Access
      The nonlinear dynamics of Taylor-Couette flow in a small aspect ratio annulus (where the length of the cylinders is half of the annular gap between them) is investigated by numerically solving the full three-dimensional ...

    • Spontaneous generation of a swirling plume in a stratified ambient 

      Marqués Truyol, Francisco; López Moscat, Juan Manuel (2014-12-01)
      Article
      Restricted access - publisher's policy
      The transition from laminar to complex spatio-temporal dynamics of plumes due to a localized buoyancy source is studied numerically. Several experiments have reported that this transition is sensitive to external perturbations. ...
