Investigation of Exothermic Behaviors of Energetic Particles in Microfluidics Channels
Scheme and representative frames of delivery, ignition, and combustion process of core@shell Al@CuO energetic material in a microchannel. The electrical discharge occurred at the throat of microchannel leads to the combustion of the energetic reaction, causing the formation of high‐momentum butterfly‐shaped jet at the throat.
