Affiliation: RWTH Aachen Academic Webpage Title: Central finite volume schemes for coupled hyperbolic models Abstract: Various real-world problems in two-phase dynamics, multi-scale processes and networks can be addressed by coupling hyperbolic models at a static interface. We propose a new relaxation based approach for the coupling of general hyperbolic systems, in which the Lax curves…
Affiliation: University of Oxford, UK Academic webpage Title: Aggregation-Diffusion Equations for Collective Behaviour in the Sciences Abstract: Many phenomena in the life sciences, ranging from the microscopic to macroscopic level, exhibit surprisingly similar structures. Behaviour at the microscopic level, including ion channel transport, chemotaxis, and angiogenesis, and behaviour at the macroscopic level, including herding of…
Affiliation: University of Strathclyde, UK Academic Webpage Title: A reduced model for a problem in non-Newtonian fluid mechanics Abstract: We propose a finite element discretisation of a three-dimensional non-Newtonian flow whose dynamics are described by an Upper Convected Maxwell model. First, a one-directional simplification of the UCM problem is made, so the main variables are…
Academic webpage: https://www.ma.imperial.ac.uk/~pberloff/ Title: Oceanic Vortex Pulsars Abstract: Theoretical studies of coherent vortices have a half-century history and in many ways have become classics of geophysical fluid dynamics. Some recent results will be presented on a new class of stable and ever-living coherent vortices on stratified background shears. These features, referred to as "vortex pulsars",…
Academic webpage: https://www.gla.ac.uk/schools/mathematicsstatistics/staff/robertteed/ Title: Numerically modelling the magnetic field generation of Earth’s core Abstract: Planetary magnetic fields are produced by dynamo action through turbulent motions of an electrically conducting fluid within the interior of the planet. Numerical experiments of dynamo action relevant to Earth's magnetic field have produced different regime branches identified within bifurcation diagrams…
Academic webpage: https://www.durham.ac.uk/staff/christopher-prior/ Title: Predicting protein dynamics using writhe Abstract: The advent of AlphaFold has steered the fundamental questions on protein structure towards understanding their dynamics in their native state, rather than the static crystal states routinely predicted. One critical tool in our arsenal is small angle x-ray scattering (SAXS) which allows, with significant modelling,…
Academic webpage: https://www.maths.ox.ac.uk/people/patrick.farrell Title: Designing conservative and accurately dissipative numerical integrators in time Abstract: Numerical methods for the simulation of transient systems with structure-preserving properties are known to exhibit greater accuracy and physical reliability, in particular over long durations. These schemes are often built on powerful geometric ideas for broad classes of problems, such as…
