The objective is to address the spray structure that preserves the flame height and modifies the width of the flame. The atomizer concept for formation of a modified spray combines a swirling liquid film generation that is atomized by an external swirling gas flow. To investigate the main characteristics of the combined atomizer, experiments and numerical simulations of the flow operation with different geometric nozzle parameters (number of gas holes) and process parameters (flow rate of liquid and gas) as well as liquid properties are carried out to produce a modified, enlarged and steady spray of small droplets. In this work, three different liquids (water without and with 40% and 60% weight of glycerol) are used as the liquid phase and air as the gas phase. In the simulations, the multiphase flow is modeled by an Eulerian-Lagrangian approach with two-way c...
