Reduced models of point vortex systems
Jonathan Maack, Bruce Turkington
Nonequilibrium statistical models of point vortex systems are constructed using an optimal closure method, and these models are employed to approximate the relaxation toward equili…
Optimal response to non-equilibrium disturbances under truncated Burgers-Hopf dynamics
Simon Thalabard, Bruce Turkington
We model and compute the average response of truncated Burgers-Hopf dynamics to finite perturbations away from the Gibbs equipartition energy spectrum using a dynamical optimizatio…
Coarse-graining two-dimensional turbulence via dynamical optimization
Bruce Turkington, Qian-Yong Chen, Simon Thalabard
A model reduction technique based on an optimization principle is employed to coarse-grain inviscid, incompressible fluid dynamics in two dimensions. In this reduction the spectral…
Optimal thermalization in a shell model of homogeneous turbulence
Simon Thalabard, Bruce Turkington
We investigate the turbulence-induced dissipation of the large scales in a statistically homogeneous flow using an "optimal closure," which one of us (BT) has recently exposed in t…
An optimization principle for deriving nonequilibrium statistical models of Hamiltonian dynamics
Bruce Turkington
A general method for deriving closed reduced models of Hamiltonian dynamical systems is developed using techniques from optimization and statistical estimation. As in standard proj…
A nonequilibrium statistical model of spectrally truncated Burgers-Hopf dynamics
Richard Kleeman, Bruce E. Turkington
Exact spectral truncations of the unforced, inviscid Burgers-Hopf equation are Hamiltonian systems with many degrees of freedom which exhibit intrinsic stochasticity and coherent s…
