چکیده انگلیسی
The effects of forced synthetic vibration on mixing in a circular flexible container were investigated numerically for a μ-TAS (Total Analysis System). The synthetic forced vibrations consisted of the mode-vibration in the normal direction to the circular wall and the rotation of node/antinodes' positions of the vibrating wall by changing the phase of piezo actuators. The synthetic vibration yielded the rotating flow in the container without mechanical rotors. An injected droplet stretched and mixed with surrounding liquid by the strained flow field. The higher stretching of the droplet occurred near the vibrating wall. The degree of the stretching increased with increasing rotation speed and mode number. We showed that the synthetic vibration could induce high strained flow fields in the container even if the Reynolds number is low.
