Research Abstract

The purpose of this study is to investigate three-dimensional boundary layer flow on a rotating disk with orbital motion. The disk rotating device as like a spin-coater is designed and is built, however the disk spins with orbital motion. The air flow in the boundary layer on the rotating disks is visualized by the oil flow method. The velocity field in the boundary layer is measured by hot-wire. As a result, it is found that the increases in the surface roughness of disk and the flow rate of droplet liquid remote the boundary layer transition. The behavior of droplets scatter shot from the edge of a rotating disk are investigated by using PTV (particle tracking velocimetry).
