The influence of fluidic effects on two different kinetic parameter identifications in lab-scale catalysis testing was investigated using computational fluid dynamics. Firstly, the dry reforming of methane in a stagnation flow reactor with a detailed surface mechanism was simulated fully three-dimensional. It is shown that the 3D simulations are not advantageous over the commonly used stagnatio...

The mathematical model of a steadily propagating Saffman-Taylor finger in a Hele-Shaw channel has applications to two-dimensional interacting streamer discharges which are aligned in a periodic array. In the streamer context, the relevant regularization on the interface is not provided by surface tension but instead has been postulated to involve a mechanism equivalent to kinetic undercooling, ...

The main mechanism responsible for Axion-Like-Particle (ALP) production in the early universe is so-called misalignment mechanism. Three regimes have been investigated this context: standard misalignment, large and kinetic misalignment. latter applies if axion inherits a initial velocity universe, such that field rolls through many wiggles during its evolution, before it gets trapped one minimu...

Institute of Nuclear Medicine, University College London, London, UK Kinetic analysis can be applied both to dynamic PET and dynamic contrast enhanced (DCE) MRI data. We have investigated the potential of combined PET-MRI kinetic modelling using simulated FDG data. The volume of distribution, Ve, for the extravascular extra-cellular space (EES) can be estimated by DCE-MRI, and used to reduce th...
