Numerical Analysis of a Quasi-Gasdynamic Algorithmas Applied to the Euler Equations

摘要

The computational properties of a quasi-gasdynamic algorithm are analyzed as applied tostrong-shock Riemann problems and acoustic disturbance propagation. It is shown that a unifiedtreatment can be given to these problems in the framework of the algorithm. Stability conditions arenumerically obtained, and the error and computational complexity of the difference scheme are esti-mated.
