| 摘 要： | 为提高烟尘净化用喷嘴的雾化性能，提出一种气液两相旋流喷嘴，用CFX软件对该喷嘴内部流场模拟的结果表明，强烈的气旋作用使液流呈环状，使气液混合流在达到喷嘴末端时易于破碎成雾。在实验室条件下，利用Winner313型喷雾激光粒度分析仪对喷嘴进行了雾化粒度测定，分析发现雾滴中位径与气液比的关系呈幂函数衰减，这一规律将有助于在工程应用时确定喷嘴工况。

| Abstract: | In order to improve the characteristics of the spray nozzle, a new kind of gas-liquid two phase rotation flow nozzle is developed. The simulation results obtained by the computing fluid software, CFX, illustrated that the liquid is changed into a rotary band due to the high gas shear strength. Therefore, the fine water droplets can be easily produced when this tow phase fluid flows to the end of the nozzle. The atomized droplet size is measured by Winner313 spray laser particle size analyzer under the laboratory conditions. The experimental data show that the relation of the spray median diameter and the gas-liquid ratio follows the power function. It is useful to determine the operation parameters in industrial application. |
