Child droplets from micro-explosion of emulsion and immiscible two-component droplets

Here we present the experimental findings of research into integral characteristics secondary droplets produced from micro-explosive fragmentation two types initial droplets. Both are based on water and tetradecane: an emulsion droplet a two-component immiscible with as core tetradecane envelope. We study threshold (critical) conditions for micro-explosion substrate heated up to 550 °C. In course experiments, recorded number, sizes, velocities, temperatures, component composition child It is shown that parameters differ significantly in case The decisive impact comes heating temperature. Using combination Schlieren Photography, Particle Tracking Velocimetry, 2-Color Laser Induced Fluorescence, have determined proportions concentration size combustible emerging aerosol cloud. also calculated kinetic energies When generalizing findings, established generation high-temperature fine mist through breakup typical trajectories fragments. show such possible both pronounced interface. much more fragments second case. This result shows separates intensely case, systems relying liquid mixing combustion chamber bear promise.
