Abstract

Computational algorithms are described to model quasi-one-dimensional non-steady flows for multicomponent reacting gas. Main feature of the technique suggested in the paper is a way to calculate trajectories of strong and weak discontinuities. The trajectories are moving computed nodes and their parameters are calculated by means of some dedicated algorithm. A software package is developed to solve problems of dynamics for reacting gas. Problems of such nature are important for applications as well as for educational purposes within the bounds of physical gas dynamics course of lectures.
