| 摘 要： | 利用LDV／APV实验系统对不同浓度NaCl溶液所形成细水雾的雾特性进行实验研究，得到不同类型细水雾在某一射流截面上的粒径分布和三维速度分布。研究表明，随着NaCl浓度的提高，在靠近射流轴线区域细水雾粒径有明显增加，而速度则显著下降。溶液浓度对细水雾动能分布的均匀性有影响。适当的添加剂配比浓度能够提高细水雾动能分布的均匀性。研究结果对评估添加剂和细水雾雾特性的影响程度有重要意义。

| Abstract: | A set of experiments was conducted to study the characteristics of fine water mist with different NaCl concentration by using LDV/APV test system. Size and three dimensional velocity distribution of fine water mist was obtained on a certain section of mist jet. With the increase of NaCl concentration, the mist size increased and the velocity decreased significantly in the zone near to jet axis. The concentration influenced the evenness of kinetic energy distribution of fine water mist. Proper concentration will be helpful to increase the evenness of the kinetic energy distribution. The results are valuable for evaluating the influence of additive on the characteristics of fine water mist. |
