Swirl atomizers are commonly used by refining and chemical companies to wash out ammonium chloride deposits. Experiments and numerical simulation were performed to investigate the atomization and mixing characteristics of swirl atomizers. The volume‐of‐fluid Lagrangian method was applied in the simulation, and its results were compared with experimental data to validate its accuracy. Results demonstrated that the entrainment effect of the airflow changed the atomization angle and coverage area of water. Momentum exchanges between water and airflow promoted the fracture of liquid membranes and formed small droplets.

炼油行业旋流雾化器的雾化和混合特性

旋流雾化器通常被精炼和化学公司用来洗去氯化铵沉积物。通过实验和数值模拟研究了旋流雾化器的雾化和混合特性。在模拟中应用了流体体积拉格朗日方法，并将其结果与实验数据进行比较以验证其准确性。结果表明，气流的夹带作用改变了水的雾化角度和覆盖面积。水和气流之间的动量交换促进了液膜的破裂并形成了小液滴。
