摘要：An experimental study was conducted on gas-particle coaxial jets by PIV and high-speed camera. The effects of the coaxial jets form and the addition of swirl on the flow and mixing characteristics of particle phase were investigated. The results showed that the axial velocity of the granular jet exposed to an annular air jet was higher than that of the granular jet with a central air jet. In addition, the mixing effect of the case with an annular air jet was found to be much better. For the two coaxial jets forms, the particle axial velocity profile in the cross-section close to the nozzle was more even. The addition of swirl, especially for the strong swirl, could not only achieve the uniform distribution of the particle axial velocity in the far field, but also improve the mixing effect of the two-phase efficiently. ?, 2015, Chemical Industry Press.
