Experimental analysis of the initial spark ignition site for the turbulent flow of aluminium-air mixture

Abstract

The paper presents an experimental analysis of the initial ignition site in the recirculation area with a turbulent flow of aluminium-air mixture ignited by an electric spark. It has been found out that the nature of initial ignition site development in a turbulent flow of aluminium-air mixture corresponds to the nature of initial site development for a homogeneous combustible mixture.
