Abstract:
1. A fluid mixing reaction enhancement method using a micro device which makes a plurality of fluids mixedly reacted by joining the fluids into one microchannel through each of a plurality of fluid supply passes, comprising: providing said microchannel; and inducing a velocity fluctuation in a microchannel longitudinal direction in the fluids by propagating infralow frequency vibration at a vibration frequency of at least 50 Hz and less than 1 kHz to the fluids which flow through an inside of the microchannel, wherein an opening width of the microchannel is at least 10 μm and not more than 1000 μm; said method further comprising: inducing velocity fluctuation in fluids which flow through the inside of the microchannel by vibrating a tube coupled to the fluid supply passes; quantitatively evaluating a mixed state in the microchannel based on a vibration speed variation strength of a tube, the vibration speed variation strength defined by the square root of a sum of time means of square of u where u
