A unified diffuse interface method for the interaction of rigid bodies with elastoplastic solids and multi-phase mixtures
Tim Wallis, Philip Barton, Nikolaos Nikiforakis
This work outlines a new multi-physics-compatible immersed rigid body method for Eulerian finite-volume simulations. To achieve this, rigid bodies are represented as a diffuse scal…
Reacting condensed phase explosives in direct contact
Riccardo Demattè, Louisa Michael, Nikolaos Nikiforakis
In this article we present a new formulation and an associated algorithm for the simultaneous numerical simulation of multiple condensed phase explosives in direct contact with eac…
Equation of state driven radiative models for simulation of lightning strikes
M. Apsley, S. T. Millmore, N. Nikiforakis
This work is concerned with the numerical simulation of plasma arc interaction with aerospace substrates under conditions akin to lightning strike and in particular with the accura…
A unified multi-phase and multi-material formulation for combustion modelling
Maria Nikodemou, Louisa Michael, Nikolaos Nikiforakis
The motivation of this work is to produce an integrated formulation for material response due to detonation wave loading. Here, we focus on elastoplastic structural response. In pa…
Ripple : Simplified Large-Scale Computation on Heterogeneous Architectures with Polymorphic Data Layout
Robert Clucas, Philip Blakely, Nikolaos Nikiforakis
GPUs are now used for a wide range of problems within HPC. However, making efficient use of the computational power available with multiple GPUs is challenging. The main challenges…
An improved equation of state for air plasma simulations
Frederik Träuble, Stephen Millmore, Nikolaos Nikiforakis
This work is concerned with the development of a novel, accurate equation of state for describing partially ionised air plasma in local thermodynamic equilibrium. One key applicati…
