Meniscus Shape and Splashing of Magnetic Fluid in Magnetic Fluid Seal.
Magnetic fluid splashing from a magnetic fluid seal due to high-speed rotation of the seal ring was experimentally investigated in relation to clearance and magnetic field strength around a gap to be sealed. Meniscus deformation, owing to fluid rotation, was accurately observed by a silhouette formed when the meniscus was illuminated with a bold laser ...
