A detailed particle model for polydisperse aggregate particles [PDF]
Journal of Computational Physics, 2019 The mathematical description of a new detailed particle model for polydisperse aggregate particles is presented. An aggregate particle is represented as a collection of overlapping spherical primary particles and the model resolves the composition ...

A Single Particle Model with Electrolyte and Side Reactions for degradation of lithium-ion batteries [PDF]
Applied Mathematical Modelling, 2022 Battery degradation, which is the reduction of performance over time, is one of the main roadblocks to the wide deployment of lithium-ion batteries.

Particle-based Ising model [PDF]
Physical Review E, 2021 We characterize equilibrium properties and relaxation dynamics of a two-dimensional lattice containing, at each site, two particles connected by a double-well potential (dumbbell). Dumbbells are oriented in the orthogonal direction with respect to the lattice plane and interact with each other through a Lennard-Jones potential truncated at the nearest ...

Multi-Scale Modelling of Fluidized Bed Biomass Gasification Using a 1d Particle Model Coupled to Cfd
Social Science Research Network, 2022 For many fluidized bed applications, the particle movement inside the reactor is accompanied by reactions at the particle scale. The current study presents for the first time in literature a multi-scale modelling approach coupling a one-dimensional ...

Particle Creation and the Schwinger Model
Symmetry, 2022 We study the particle creation process in the Schwinger model coupled with an external classical source. One can approach the problem by taking advantage of the fact that the full quantized model is solvable and equivalent to a (massive) gauge field with a non-local effective action.

Decoherence in a two-particle model [PDF]
Journal of Mathematical Physics, 2004 We consider a simple one-dimensional quantum system consisting of a heavy and a light particle interacting via a point interaction. The initial state is chosen to be a product state, with the heavy particle described by a coherent superposition of two spatially separated wave packets with opposite momentum and the light particle localized in the region

A Relativistic Particle Model of the H-Atom [PDF]
, 2022 A relativistic classical particle model of the H-atom is presented. The balance of the electrostatic field and the spacetime field generates a quantized atom of singular radius. The radius is quantized due to the quantized nature of the electric charge.

Continuum modelling of granular particle flow with inelastic inter-particle collisions [PDF]
, 2003 The kinetic theory of granular flow is a successful model for gas-solid flows. However, inelastic collisions between particles, among other mechanisms, cause agglomeration of particles, which may be the reason why undue sensitivity of the model to any ...
