The paper “A symplectic integrator for dynamic coupling between nonlinear vessel motion with variable cross-section and bottom topography and interior shallow-water sloshing“, authored by Hamid Alemi Ardakani, has been accepted for publication in the Journal of Fluids and Structures.  The paper introduces a symplectic integrator for simulation of the coupled motion between shallow-water sloshing in […]

Congratulations to Katie Cranfield who passed her PhD viva today with minor corrections.  The title of her thesis is “Bayesian methods for personalising therapies for individuals with type 2 diabetes“.  The external examiner was Jim Griffin (Kent) and the internal examiner was Janet Godolphin.  Her supervisors were Naratip Santitissadeekorn and Ian Roulstone for the final […]

The FMS group at Surrey is hosting a two-day conference on “Coupling moist convection and large scale dynamics in numerical weather prediction models”, organised by Ian Roulstone, Alison Stirling (UK Metoffice), Peter Clark (Reading), Matt Turner, and Bin Cheng. This conference is sponsored by the Maths Foresees EPSRC Network and the University of Surrey. It […]

The paper “Shallow-water sloshing in a moving vessel with variable cross-section and wetting-drying using an extension of George’s well-balanced finite volume solver” with authors Hamid Alemi Ardakani, Tom Bridges and Matt Turner has been accepted for publication in the Journal of Computational Physics.  The shallow-water equations in a moving vessel with variable bottom topography and […]

The paper “Numerical simulations of dynamic coupling between shallow-water sloshing and horizontal vessel motion with baffles“, co-authored by Hamid Alemi Ardakani and Matt Turner has been accepted for publication in Fluids Dynamics Research. In the paper, they investigate shallow water sloshing in a baffled vessel numerically using a geometric integration scheme. In particular the response […]

The paper “Exponential estimates of symplectic slow manifolds“, co-authored by Claudia Wulff and Kristian Uldall Kristiansen (Danish Technical University) has been accepted for publication in the Journal of Differential Equations. Final form preprint is arXiv-ed here. In the paper, they prove the existence of an almost invariant symplectic slow manifold for analytic Hamiltonian slow-fast systems with […]
