Bounds on heat transport for convection driven by internal heating
Ali Arslan, Giovanni Fantuzzi, John Craske +1
The mean vertical heat transport in convection between isothermal plates driven by uniform internal heating is investigated by means of rigorous bounds. These…
Unified description of turbulent entrainment
Maarten van Reeuwijk, J. Christos Vassilicos, John Craske
We present a mathematical description of turbulent entrainment that is applicable to free shear problems that evolve in space, time or both. Defining the global entrainment velocit…
Many-body physics with ultracold plasmas: Quenched randomness and localization
John Sous, Edward Grant
The exploration of large-scale many-body phenomena in quantum materials has produced many important experimental discoveries, including novel states of entanglement, topology and q…
The entrainment and energetics of turbulent plumes in a confined space
John Craske, Megan S. Davies Wykes
We analyse the entrainment and energetics of equal and opposite axisymmetric turbulent air plumes in a vertically confined space at a Rayleigh number of using t…
Adjoint chaos via cumulant truncation
John Craske
We describe a simple and systematic method for obtaining approximate sensitivity information from a chaotic dynamical system using a hierarchy of cumulant equations. The resulting…
