概要

As a first stage of developing the micro non-element chaotic mixer, mixing behavior in the micro channel where pulsating subsidiary stream meets main stream at one points instead of a few points is investigated in the present study. The folding and stretching trajectories that potentially lead to the chaotic trajectories are observed. The present non-element chaotic mixer is shown to reduce mixing time. It should be noted that the even one pulsated subsidiary stream enhance the product ratio up to 1.3 time larger than that without pulsation. Experimental observations show that smaller duty ratio of pulsation induce more folding and stretching of material lines.
