WebbHeuristic arguments are presented to support our choice of bounds. We derive first-order schemes which use these approximate Riemann solutions and show their relationship to known finite difference schemes.Next, we use the approach of van Leer et al. [1] to construct second-order schemes based on these approximate Riemann solutions. WebbWe describe a new Godunov algorithm for relativistic magnetohydrodynamics (RMHD) that combines a simple, unsplit second order accurate integrator with the constrained …
WebbA simple second order accurate and fully Eulerian numerical method is presented for the simulation of multifluid compressible flows, governed by the stiffened gas equation of state, in hydrodynamic regime.

The early versions by Colella and Woodward (PPM) and van Leer (MUSCL) are described in their original form. The simplification of these by Roe, based on approximate Riemann solver, is then …
Webb3 feb. 1999 · The ignition model describes the various phenomena occurring at the microscopic scale during viscoplastic pore collapse. The growth stage is represented by a model combining inner combustion inside the pores and outer combustion on the surface of the grains. These microscopic models are incorporated into a macroscopic one.
