Finite Volume Modelling of Compressible Inviscid Flows Using Runge-Kutta Time-Stepping Schemes
by the Runge-Kutta schemes, two types of artificial dissipation are added - Jameson's artificialdissipation and TVD-type of artificial dissipation. Several different approaches of adding...

Numerical Solution of Steady and Unsteady Flow over a Profile in a Channel
The work deals with steady and unseady solution of subsonic flow over a porfile DCA 18% in a channel. For the computation the predictor-corrector MacCormack scheme with modified TVD Causon's artificial dissipation is used. ...

A Symmetry Preserving Dissipative Artificial Viscosity in an r-z Staggered Lagrangian Discretization
We present an artificial viscous force for two-dimensional axi-symmetric r-z geometry and logically rectangular grids that is dissipative, conserves the z-component of momentum and preserves spherical symmetry on an equi-angular pol...

Modern computational methods of compressible fluid flow.
The cell-centred finite volume formulation of the explicit two - step TVD Mac Cormack scheme proposed by Causon on a structured quadrilateral grid and its modification, which uses less artificial viscosity, is desvribed in this cont...

A symmetry preserving dissipative artificial viscosity in r-z geometry
We present a novel artificial viscosity for staggered Lagrangian schemes in 2D axi-symmetric r-z geometry on logically rectangular grids. The suggested viscous force is dissipative by construction, conserves both components of momen...
