概要

In the field of industrial cleaning, solvents like Freon have been used widely. But such solvents will be prohibited soon from a viewpoint of environmental problem. Some cleaning methods not using solvents have been developed recently. One of them is the cleaning method using cavitation jet. It utilizes the impulse force when cavitation bubbles collapse. But it needs high pressure over 20 MPa in order to generate cavitation bubble. We knew from our last study that we could generate cavitation bubble at low pressure below 1 MPa with micro-bubble generator. In this study, we confirmed whether these bubbles from micro-bubble generator had the same effect as the bubbles from cavitation jet. As a results, we realized that the micro-bubbles at low pressure did not make impulse force as the cavitation bubbles at high pressure and were not useful for cleaning.
