Effects of Cavitation Ring Formed on Laser-Textured Surface of Mechanical Seal

It is considered that cavitation plays an important role in maintaining the sealing performance of mechanical seals. However, there are not any studies that demonstrated how to control cavitation regions and take advantage of them to improve the sealing performance of mechanical seals. In this study...
