| 摘要: |
| 本文根据附面层理论，对高速气流中的液滴，因气流和液滴表面相互作用而产生的气动剥离现象进行了分析，建立了气液两相附面层耦合问题的理论分析模型，得到了发生气动剥离时的最小气流速度的计算公式，为液体燃料在高速气流中雾化机理研究提供参考。 |

| Abstract: |
| Based on the boundary layer theory in this paper，a theoretical model for the coupling problem of two phase boundary layer of gas and droplet has been established. A formula to calculate the minimum velocity of gasflow needed to start the aerodynamic stripping has been obtained for the problem of the aerodynamic stripping，which is a result from the interaction between gas and a droplet surface when the droplet is in a high speed gas flow. This paper could be a useful to the investigation of atomizing mechanism of liquid fuel in high speed gas flow. |
