Implicit total variation diminishing (TVD) schemes for steady-state calculations [PDF]

open access: yes6th Computational Fluid Dynamics Conference Danvers, 1983
The application of a new implicit unconditionally stable high-resolution TVD scheme to steady-state calculations is examined. It is a member of a one-parameter family of explicit and implicit second-order accurate schemes developed by the third author [ibid.

A cosmological hydrodynamic code based on the total variation diminishing scheme [PDF]

open access: yesThe Astrophysical Journal, 1993
An explicitly second-order finite difference code based on a total variation diminishing scheme for self-gravitating cosmological hydrodynamic systems is described. The code was developed to follow correctly the adiabatic changes of extremely supersonic preshock flows with a Mach number larger than 100 as well as very strong shocks.

A hybrid numerical scheme for extended Boussinesq equations

open access: yesShui kexue jinzhan, 2013
To efficiently solve the extended Boussinesq equations,a hybrid finite-difference and finite-volume scheme is developed. The one-dimensional governing equations are kept in conservation form.

Flow modelling in a straight rigid-walled duct with two rectangular axisymmetric narrowings. Part 2. An alternative approach

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2021
A second-order technique is suggested to study fluid motion in a two-dimensional hard-walled duct with two abrupt constrictions. In this technique, the governing relationships are integrated via their rewriting in a non-dimensional form, deriving their ...

Positivity of an explicit Runge–Kutta method

open access: yesAin Shams Engineering Journal, 2015
This paper deals with the numerical solution of initial value problems (IVPs), for systems of ordinary differential equations (ODEs), by an explicit fourth-order Runge–Kutta method (we will refer to it as the classical fourth-order method) with special ...

High order TVD scheme for hyperbolic conservation laws [PDF]

open access: yesAlfarama Journal of Basic & Applied Sciences, 2020
In this paper, we introduced a new third order finite difference scheme for solving initial value problems for hyperbolic conservation laws. This method is a finite difference scheme combining a dissipative scheme (diffusion scheme) and a dispersive ...
