Numerical calculations in a fully expanded jet and coaxialjets were performed with a computer.
并且，对轴对称充分扩展喷注和共轴喷注分别进行了相应的数值计算。
2
The mixing ratio of coaxialjets increases comparatively because of the synthetic jet actuators, and the mixing effects in coaxialjets also become more agreeable.
合成射流激励器的采用可使共轴射流截面掺混率比未加激励时 得到增加，增强了共轴射流的掺混效果。

The effect of cross angles and density ratios on coaxial cross jets flow fields was investigated by using Dual PDA.
