| 摘 要： | 文章基于双流体模型,并采用ANSYS/CFD多组分传输包分析了颗粒群与压缩气流相互作用下喷涂飞行区内的速度分布。结果表明,双相流的速度分布与单独压缩气流的速度分布大致相似,即在开始的一段喷涂距离内速度降低很快,随后趋于平缓;而在相同的喷涂距离下,与喷涂轴线的夹角越大,其所对应的速度越小。但在喷涂入口处,双相流速度分布具有一段明显的加速段。

| Abstract: | The velocity distribution in the spray cone is analyzed by using the ANSYS/CFD multiple species transport program based on the two-phase flow model.The results indicate that the velocity distribution of the two-phase flow is very similar to the gas velocity distribution.At the beginning, the velocity drops very quickly,and then become mild;while at the same spray distance,the velocity will drop down when the angle becomes larger.But at the threshold of the injet,the two-phase flow's velocity distribution has a considerable speed-up region. |
