Аннотация

The paper is devoted to the numerical analysis of the gaseous combustion process in a channel willed with the hydrogen-air mixture with the inflow of a fresh mixture seeded with microdroplets of water. The dynamics of microdroplets are described in the Lagrangian approximation, which makes it possible to identify the role of local interaction between the droplets and the flame front. It has been shown that the impact of droplets on the front can provoke the generation of disturbances of the flame front and intensify the development of front instability, thereby causing an integral increase in the combustion rate. Using spectral analysis of the structure of the front in the presence of microdroplets, the dynamics of the development of individual harmonics of front disturbances was analyzed and the mechanisms of evolution of the flame front under the influence of microdroplets of water were identified.
