ボルテックスマイクロミキサーにおける二液混合

抄録

In this study, a numerical analysis was performed to simulate two-liquid flow in a vortex micromixer under different flow condition. The micromixer is composed of a microchannel and a vortex chamber with 4 inlets. Each of the liquids is introduced through 2 alternative inlets, and then they are allowed to pre-mix in the vortex chamber before entering the channel. The length of the vortex chamber was changed to investigate the optimal mixing performance. As a result, the length of the vortex chamber shown a significant influence on the mixing performance, and the longer chamber obtained a higher mixing index.
