MCFL-Chem software module for numerical simulation of high-speed reacting flows
Abstract:
In this paper we present a computational model for high-speed multicomponent flows of reacting gases mixtures, which formed the core of the MCFL-Chem software module. The system of Navier–Stokes equations for a multicomponent reacting gas is used as a mathematical model; chemical reactions are described by a detailed kinetic scheme. The general solution algorithm is based on the splitting scheme for the types of processes under consideration: convection–diffusion–chemical reactions, an approach based on the modified method of S.K. Godunov is used. The present work continues the previous studies of the authors on numerical simulation of multicomponent gas mixtures flows, in this work we focus on the implementation of the chemical reactions module, its implementation in the general algorithm, validation and verification tests.
