An entropy scheme for a gas-dynamic calculation
USSR Computational Mathematics and Mathematical Physics, 1969Abstract THE usual requirements for difference schemes (in particular for the gas-dynamic equations) are approximation and stability. The solutions of concrete equations, however, have a number of important qualitative features; the satisfaction of the above requirements is far from always being a guarantee that they can be transferred to finite ...

Gas-dynamic calculation of pulsating flow in pipelines
Journal of Applied Mechanics and Technical Physics, 1972A numerical solution is examined for a system of equations of one-dimensional isothermal flow of a perfect gas in a horizontal pipe with a periodically varying function of the flow rate at the boundary. The numerical solution is compared with the solution of the linearized problem. The results can be used to calculate the pulsating motion of gas in the

Methods for the Gas Dynamic Calculation of the Cooled Multistage Turbine Performance
Volume 2C: Turbomachinery, 2014Method of 1D calculation was developed. It is applicable to various ideal gases and their mixtures with regard to variability of their physical properties within wide temperature range. Four checking cross-sections were set for each vane/blade row: at the row inlet, in the row throat, at the row outlet, and downstream the row at the ...

A technique for the gas dynamic calculation of the cooled multistage turbine performance
Russian Aeronautics (Iz VUZ), 2015A technique of one-dimensional turbine performance calculation, implemented into a quick-operating computational code, is stated. Analytical relations for a flow outlet angle calculation as well as semi-empirical relations for taking into account various types of energy losses and cooling are applied.

On the Accuracy of Discontinuous Galerkin Method Calculating Gas-Dynamic Shock Waves
Doklady Mathematics, 2023The results of a numerical calculation of gas-dynamic shock waves that arise when solving the Cauchy problem with smooth periodic initial data are presented using three variants of the DG (Discontinuous Galerkin) method, in which the solution is sought in the form of a piecewise linear discontinuous function.

ON THE INTEGRAL CONVERGENCE OF NUMERICAL SCHEMES CALCULATING GAS-DYNAMIC SHOCK WAVES
Доклады Российской академии наук. Математика, информатика, процессы управления, 2023A comparative experimental accuracy study of shock-capturing schemes such as RBM(Rusanov-Burstein-Mirin), CWA(Compact high order Weak Approximation) and A-WENO(Alternative Weighted Essentially Non-Oscillatory) schemes is carried out by numerically solving a Cauchy problem with smooth periodic initial data for the Euler equations of gas dynamics.

Kinetic algorithms for calculating gas dynamic flows
USSR Computational Mathematics and Mathematical Physics, 1985Abstract Differential-difference systems of equations for describing gas-dynamic flows are obtained on the basis of a kinetic model. Methods of calculation are considered and examples of the numerical solution of several problems are presented.
