Fizzy jets are effervescent streams of liquid aerated with dispersed gas, producing bubbly, turbulent flows that enhances atomization by generating a vast array of chaotic interfacial features. These jets generate droplets spanning a broad size distribution with irregular residual blobs that survive the aerodynamic turmoil. Introducing shock waves to this further enhances fragmentation, presenting more uniform disintegration and intricate flow dynamics. This configuration involves chaotic interactions between irregular liquid structures and high-speed gas flows, leading to improved atomization and numerous practical applications.
