The final goal of this research is to establish the method for mass and energy transport with inhibiting its diffusion using a coaxial jet. The authors confirmed that the diffusion inhibition effect of the central round jet can be obtained when the velocity ratio of the round jet to the annular jet is set to less than 1. Furthermore, it was clarified that the inhibition effect is related to the change in the vortex structure formation process due to the change in velocity ratio and the advection effect due to the annular jet. This indicates that the vortex structure formed in the jet flow field is deeply related to the diffusion inhibition effect of the coaxial jet. The purpose of this study is to confirm the three-dimensional vortex structure of a coaxial jet at the low velocity ratio experimentally.
