摘要
荷电喷雾可以有效地改善雾化质量和喷雾流场特性,因此被广泛地应用于静电喷涂、除尘、药物喷洒和液体燃料的雾化燃烧等领域 荷电喷雾湍流射流流场的数值模拟对于荷电喷雾装置的设计及确定射流喷雾的各特性参数具有重要意义 采用颗粒拟流体方法,用k ε kp荷电两相湍流模型对荷电喷雾气液两相湍流流场进行了数值模拟 经与实验结果对比,该模型可以较好地模拟荷电气液两相湍流射流流场。
Electrostatic spray can improve the quality and the field properties of liquid atomization efficiently, thus it has been used widely in spray coating, pesticide spraying, dust control and spray combustion. Numerical modeling of the flow field for the charged two-phase turbulent jet is important to the design of electrostatic spray equipment. In this study, multi-fluid k-ε-k_p two-phase turbulence model is used to simulate charged gas-liquid two-phase coaxial jet. Comparing the modeling results with experiments, the charged gas-liquid two-phase turbulence can be well predicted by this model, which can be used in the design of electrostatic sprayer.
