Application of dissipation-free numerical method CABARET for solving gasdynamics of combustion and detonation

Abstract

This paper discusses capabilities of the novel dissipation-free CABARET numerical algorithm to solve the range of complex non-stationary combustion problems. On the basis of detailed analysis of the obtained results and comparison with the data derived with the classic low-order coarse particles method it was shown that reactive flow evolution process may be strongly influenced by the artificial effects introduced by the numerical algorithm, numerical dissipation in particular. Revealed peculiarities of the flame propagation dynamics regimes taking place in considered tests allowed us to propose a number of requirements which should be taken into account when choosing numerical procedure suitable for modelling combustion processes in real technical environment.
