To implement a pulse combustion process in a flow of aerosolized particles, flow aerodynamics investigation and determination of the time of aluminum particle residence in a sudden expansion combustion chamber was conducted. The identified flow aerodynamics features and obtained values of the local residence time of aluminum particles made it possible to develop a combustion chamber for a pulse power plant. The temperature field of a pulsed aluminum-air flame was obtained and the type of temperature-time relationship along the flame axis was established in the course of plant tests. Integrated radiation flux density and distribution of radiant energy intensity of a pulsed aluminum-air flame was determined in the wavelength spectral range λ = 1.0 … 4.5 μm. The investigation results obtained in this work can be applied to create pulse power plants fired with powdered metal combustible.
