Mixed baroclinic convection in a cavity
Abhishek Kumar, Alban Pothérat
We study the convective patterns that arise in a nearly semi-cylindrical cavity fed in with hot fluid at the upper boundary, bounded by a cold, porous semi-circular boundary at the…
Boundary Zonal Flow in Rotating Turbulent Rayleigh-Bénard Convection
Xuan Zhang, Dennis P. M. van Gils, Susanne Horn +7
For rapidly rotating turbulent Rayleigh--Bénard convection in a slender cylindrical cell, experiments and direct numerical simulations reveal a boundary zonal flow (BZF) that repla…
Turbulence in a stably stratified fluid: Onset of global anisotropy as a function of the Richardson number
Jayanta K. Bhattacharjee, Abhishek Kumar, Mahendra K. Verma
It is necessary to introduce an external forcing to induce turbulence in a stably stratified fluid. The Heisenberg eddy viscosity technique should in this case suffice to calculate…
Transition between advection and inertial wave propagation in rotating turbulence
J. A. Brons, P. J. Thomas, A. Potherat
In turbulent flows subject to strong background rotation, the advective mechanisms of turbulence are superseded by the propagation of inertial waves, as the effects of rotation bec…
Interfacial dynamics and pinch-off singularities for axially symmetric Darcy flow
Liam C. Morrow, Michael C. Dallaston, Scott W. McCue
We study a model for the evolution of an axially symmetric bubble of inviscid fluid in a homogeneous porous medium otherwise saturated with a viscous fluid. The model is a moving b…
Simultaneous Eulerian-Lagrangian velocity measurements of particulate pipe flow in transitional regime
Sanjay Singh, Alban Pothérat, Chris C. T. Pringle +2
We present a unique pipe flow rig capable where simultaneous particle tracking and flow velocity measurements in a dilute, neutrally buoyant particulate pipe flow in regimes of tra…
