Abstract

This work considers issues related to the numeric simulation of high-speed combustion and detonation of mixtures of carbonic fuel with air. Model problems are used to study the applicability of global kinetic mechanisms to describe the detonation of a propane-air fuel mixture. Problems of finding equilibrium adiabatic lines, determining Chapman-Jouguet detonation parameters, and the simulation of the structure of a stationary detonation wave were considered. Applying global kinetic mechanisms with irreversible chemical reactions may lead to overestimation of the detonation velocity and temperature of combustion products.
