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申雾化机理研究提供参考。
Based on the boundary layer theory in this paper,a theoretical model for the coupling prob-lem of two phase boundary layer of gas and droplet has been established.A formula to calculatethe minimum velocity of gasflow needed to start the aerodynamic stripping has been obtained forthe problem of the aerodynamic stripping,which is a result from the interaction between gas anda droplet surface when the droplet is in a high speed gas flow.This paper could be a useful to theinvestigation of atomizing mechanism of liquid fuel in high speed gas flow.
