A5.3 - Velocity Measurements of Gap Flows at a Computer Hard Disk Model

J. Czarske, L. Büttner, K. Shirai & S. Obi
The gap flow in the tip clearance of a hard disk drive model has been investigated with optical measurment techniques. The flow was driven by co-rotating disks inside a cylindrical enclosure in order to simulate a hard disk drive for data storage devices. The main focus of the investigation was the understanding of the complex flow behaviors in the narrow region between the disk tip and the outer shroud wall, which is supposed to be...
