采用标准的 SIMPLEC方法 ,对基于二维、非定常、不可压缩、粘性计算模型的双微射流相互作用形成的合成流场进行了数值分析。计算结果说明 ,在一定的斯特劳哈尔数和雷诺数下、与单作动器形成的流场不同 ,双微射流合成流场受双作动器工作时的相位差影响。存在相位差时 ,合成流场不再呈对称分布 ,而偏向相位超前的一侧 The standard SIMPLEC method is used to analyze the synthetic flow field formed by the interaction of two micro-jet flows based on 2D, unsteady, incompressible and viscous computational models. The calculation results show that the flow field of the dual micro-jet flow is affected by the phase difference of the double actuator at a certain Strouhal number and Reynolds number, which is different from the flow field formed by a single actuator. When there is phase difference, the synthetic flow field is no longer symmetrical distribution, but the bias phase ahead of the side
