Analysis of droplet behavior on a rotating surface in atomization-based cutting fluid systems for micro-machining
… indicate that a cutting fluid with low surface tension and low viscosity generates lower cutting temperatures whereas a fluid with low surface tension and high viscosity generates lower cutting forces. Since in most machining processes, either the workpiece or the tool is rotating, …

Stability and transition of three-dimensional rotating boundary layers
The flow over a rotating cone in still fluid is susceptible to crossflow and centrifugal instability modes of spiral nature, depending on the cone half-angle. For parameters ranging from propeller nose cones to rotating disks, the instability triggers co-rotating vortices, whereas for slender …

Fibre optic sensor for speed measurement
… 1993) which relies on a magnet attached to a rotating surface yielding an averaged speed reading over several revolutions. The optical speed sensor requires incoherent light, conveniently provided by two low cost 780 nm CD-type laser diodes. The light was directed through a pair of spatially …

Thermodynamic Measurements by Gas-Liquid Chromatography
… with studying the separating efficiency of a rotating gas liquid chromatographic unit. This consisted of 44 20cm long, 2.5 cm ID tubes arranged in a circular bundle that rotated in the opposite direction to the flow of the carrier gas. The liquid feed, commercial turpentine with α and β …
