<p>Cleaning technology is widely used to remove oil or resist from metal and semiconductor and soon. However, it causes high cost and severe environmental impacts because of the sewage disposal. Owing to strong oxidizing ability and self-decomposing power, ozone micro-bubbles generated by a Venturi tube was proposed. The purpose of this study is to research the capability of ozone micro-bubbles and improve the cleaning mechanism. In this study, we focus on the microbubble generator with a Venturi tube. We visualized the Venturi Tube by a high-speed camera to measure the bubble diameter. We also measure the shear stress near the test piece surface by using PIV. And by titration with Potassium iodide, ozonated water and ozone gas concentration are measured. Ozone gas is well dissolved after passing through the Venturi tube. Also, brass test pieces applied with cutting oil and latex resin are washed by using bubbly flow with ozone micro-bubbles. It has been confirmed that ozone micro-bubbles are able to clean the test pieces efficiently.</p>
