Numerical solution of special ultra-relativistic Euler equations using central upwind scheme

open access: yesResults in Physics, 2018
This article is concerned with the numerical approximation of one and two-dimensional special ultra-relativistic Euler equations. The governing equations are coupled first-order nonlinear hyperbolic partial differential equations.

On the many-body problem with short-range interaction

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2022
The classical problem of the interaction of charged particles is considered in the framework of the concept of short-range interaction. Difficulties in the mathematical description of short-range interaction are discussed, for which it is necessary to ...

A splitting approach for the fully nonlinear and weakly dispersive Green-Naghdi model [PDF]

open access: yes, 2010
The fully nonlinear and weakly dispersive Green-Naghdi model for shallow water waves of large amplitude is studied. The original model is first recast under a new formulation more suitable for numerical resolution.

ADER-WENO Finite Volume Schemes with Space-Time Adaptive Mesh Refinement [PDF]

open access: yes, 2015
We present the first high order one-step ADER-WENO finite volume scheme with Adaptive Mesh Refinement (AMR) in multiple space dimensions. High order spatial accuracy is obtained through a WENO reconstruction, while a high order one-step time ...

Wave Solutions

open access: yes, 2012
In classical continuum physics, a wave is a mechanical disturbance. Whether the disturbance is stationary or traveling and whether it is caused by the motion of atoms and molecules or the vibration of a lattice structure, a wave can be understood as a ...

Structural stability of Supersonic solutions to the Euler-Poisson system

open access: yes, 2019
The well-posedness for the supersonic solutions of the Euler-Poisson system for hydrodynamical model in semiconductor devices and plasmas is studied in this paper. We first reformulate the Euler-Poisson system in the supersonic region into a second order

On the construction and properties of WENO schemes order five, seven, nine, eleven and thirteen. Part 2. Numerical examples [PDF]

open access: yesКомпьютерные исследования и моделирование, 2016
WENO schemes (weighted, essentially non oscillating) are currently having a wide range of applications as approximate high order schemes for discontinuous solutions of partial differential equations. These schemes are used for direct numerical simulation
