The Reynolds number of the flow in a micro fluidic device is low. Therefore, it is necessary to promote the mixing by some methods. This paper reports on the research to promote mixing by bubbles generated by an electric heater. We performed the visualization of mixing two fluids, colored with white and black paints respectively, in the micro fluidic device. Brightness of the fluid was observed with a CCD microscope. The image was analyzed with a personal computer, and the mixing rate was examined quantitatively. When microbubble emission boiling occurs on the heater, the mixing increased drastically. In contrast, the ordinal nucleate boiling did not enhance the mixing.
