On the Accuracy of Shock-Capturing Schemes Calculating Gas-Dynamic Shock Waves
Журнал вычислительной математики и математической физики, 2023A comparative experimental accuracy study of three shock-capturing schemes (the second-order CABARET, third-order Rusanov, and fifth-order in space third-order in time A-WENO schemes) is carried out by numerically solving a Cauchy problem with smooth periodic initial data for the Euler equations of gas dynamics.

AN ACCURATE SCHEME FOR GAS DYNAMICAL CALCULATIONS
International Journal of Computational Engineering Science, 2003An accurate numerical method is developed for computing inviscid flows containing discontinuities. The method is based on flux vector splitting (FVS) and a third-order accurate upwind-biased compact finite-difference scheme. Two different flux splitting techniques, namely, the kinetic flux vector splitting (KFVS) and van Leer's flux splitting, are used

Calculation of the characteristics of a gas-dynamic laser
Journal of Applied Mechanics and Technical Physics, 1974The dependence of the radiated power on the characteristics of optical cavities in the case of flow systems has been investigated in a number of papers [1–3], in which it is assumed that population inversion of the laser levels is obtained until entry into the cavity.

Convergence issues on fully-coupled radiative gas dynamic calculations
38th Aerospace Sciences Meeting and Exhibit, 2000Convergence problems on the fully-coupled calculation of strongly radiating hypersonic flowfields are discussed. Calculations are conducted for the inviscid flow over an axisymmetric blunt body of 1.5m nose radius. The case of the flow Mach number 46.8 is considered.

Numerical gas-dynamical calculation of turbulent mixing of the interface
USSR Computational Mathematics and Mathematical Physics, 1976Abstract TURBULENT mixing of the interface of two gases (liquids) of different density is considered. The results of [1] are generalized to the adiabatic case. A difference method is constructed. Examples of calculations of motions allowing for turbulent mixing are presented.

Numerical Calculation of Stationary Subsonic Gas Dynamics Problems
1990The present work considers algorithm of numerical solution of the problems on two-dimensional subsonic ideal gas flows in channels of complicated shape with inlet, outlet and impemeable parts on the boundary. At present the problems on steady ideal gas flows are most often solved by the stabilization method which as a solution of stationary equations ...

One-dimensional compressible gas dynamics calculations using the Boltzmann equation
Journal of Computational Physics, 1981One-dimensional inviscid gas dynamics computations are made using a new method to solve the Boltzmann equation. The numerical method is explicit and is based on concepts from the kinetic theory of gases. The gas density, velocity and temperature are computed by integrating numerically the molecular velocity distribution function.

Calculation of waves of finite amplitude in the gas dynamic approximation
Fluid Dynamics, 1986A study is made of the third (gasdynamic) approximation in the theory of waves of finite amplitude [1–3]. The evolution equation obtained for the velocity of the gas is integrated analytically. By way of example two well-known problems are considered, the propagation of a steady symmetric density discontinuity [2], and the quantitative description of ...

Application of Front Tracking to Two-Dimensional Gas Dynamics Calculations
1983We present the results from some validation tests for a two-dimensional front tracking code for gas dynamics. We study initial value problems with circularly symmetric initial data and compare the results to those obtained by a one-dimensional calculation exploiting the circular symmetry.
