The micro-bubble is an extremely small bubble whose diameter is roughly of 10μm to 100μm. Many applications of the micro-bubble have been developed in a lot of fields. It is useful to generate a large quantity of micro-bubbles effectively for future development of micro-bubble technology. In the present experiment, two swirl-type micro-bubble generators are used. These are placed face-to-face to strengthen the relative swirl shearing force. The distance between two generators is changed and diameters of bubbles are measured by taking photographs and their image processing. As a result, it is found that the jet and swirling flow deeply participate in the generation of micro-bubbles, and a large amount of micro-bubbles are generated when the distance between two devices is about the same size of the exit diameter of the generator.
