A geometric look at MHD and the Braginsky dynamo
Andrew D. Gilbert, Jacques Vanneste
This paper considers magnetohydrodynamics (MHD) and some of its applications from the perspective of differential geometry, considering the dynamics of an ideal fluid flow and magn…
Bayesian inference of ocean diffusivity from Lagrangian trajectory data
Y. K. Ying, J. R. Maddison, J. Vanneste
A Bayesian approach is developed for the inference of an eddy-diffusivity field from Lagrangian trajectory data. The motion of Lagrangian particles is modelled by a stochastic diff…
Dispersion in the large-deviation regime. Part II: cellular flow at large Péclet number
P. H. Haynes, J. Vanneste
A standard model for the study of scalar dispersion through advection and molecular diffusion is a two-dimensional periodic flow with closed streamlines inside periodic cells. Over…
Dispersion in the large-deviation regime. Part I: shear flows and periodic flows
P. H. Haynes, J. Vanneste
The dispersion of a passive scalar in a fluid through the combined action of advection and molecular diffusion is often described as a diffusive process, with an effective diffusiv…
Estimating generalised Lyapunov exponents for products of random matrices
J. Vanneste
We discuss several techniques for the evaluation of the generalised Lyapunov exponents which characterise the growth of products of random matrices in the large-deviation regime. A…
