The liquid break-up and spray combustion in supersonic crossflow are primarily encountered in scramjet engines. An aerated liquid jet injector can be considered as the effective way enhancing the liquid break-up and atomize in certain time. The atomization characteristics by varying the gas liquid ratio (GLR), which represents the ratio of gas to liquid in the aerator, is investigated. The numerical results are compared with the experimental data for GLR 0%, 4%, and 8%. This study aims to provide a comprehensive simulation of the processes of ligament and droplet breakup and atomization, employing the homogeneous mixture model (HMM) and large eddy simulation (LES). Furthermore, numerical techniques are applied, including the Novel-Abel Stiffened Gas (NASG) state equation, Adaptive Mesh Refinement (AMR), Synthetic Eddy Method (SEM), and the Eulerian-Lagrangian (EtoL) transformation.
