Abstract
This paper presents experimental data on the ignition induction period of synthetic hydrocarbons at various temperatures and pressures obtained using a shock tube. The influence of the ignition induction period on the combustion completeness of hydrocarbons in high-enthalpy flows for diffusion-kinetic regimes was determined based on the experimental results. An integral mathematical model is presented that takes into account the influence of the kinetic factors of ignition and combustion on the completeness of physicochemical processes in the air flow. The results of calculations of the combustion completeness of synthetic hydrocarbons in flows with different parameters.
