A blurred interface formulation of The Reference Map Technique for Fluid-Solid Interactions and Fluid-Solid-Solid Interactions
In this work we present a blurred interface method for Fluid-Solid Interactions (FSI) and multiple solids immersed in a fluid or FSSI (Fluid-Solid-Solid Interactions) based on the reference map technique as presented by Kamrin and Rycroft. I will follow the chain of thought which lead from the …

Numerical modelling of plasmas formed and magnetically controlled in hypersonic flows
… electrically conductive, magnetically influenced fluid. This work makes advances in numerical modelling methodologies, combined with an advanced air-plasma equation of state, to permit the realistic and efficient simulation of hypersonically formed plasmas with imposed MHD effects. The …

Mathematical and Computational Models for Transient Magnetohydrodynamic Flows of Magnetically Confined Plasmas
… both in space and time. A key element of this methodology is the discretisation of topologically complex rigid boundaries as well as material and state of matter interfaces, which represents a significant departure from current, segregated solutions on physics-driven mesh alignment. This is …

Acceleration of Eulerian Multi-Material Methods on Highly Parallel Compute Architectures
… numerical schemes commonly used in finite-volume methods, the solution of the Eikonal equation in a narrow band, the Ghost Fluid Method (GFM), and signed-distance function generation from multiple external geometry file types. Additionally, we present the main problems involved in scaling …

A Runge Kutta Discontinuous Galerkin-Direct Ghost Fluid (RKDG-DGF) Method to Near-field Early-time Underwater Explosion (UNDEX) Simulations
… compressible, inviscid and adiabatic flow, the fluid flow is governed by a set of Euler fluid equations. In practical simulations, we often encounter computational difficulties that include large displacements, shocks, multi-fluid flows with cavitation, spurious waves reflecting from boundaries …
