Characteristics of a Falling Liquid Film Flow Using Periodic Jetting Flow

Chemical Engineering Transactions, 2019
This work tried to form a falling thin film by supplying liquid to the disk attached to the upper part of the device, rotating the disk and jetting liquid onto the wall surface in order to develop a new falling film evaporator without contamination. Heat

The Influence of Specimen Misalignment on Wear in Conforming Pin on Disk Tests [PDF]

, 2004
A pin-on-disk test apparatus was modified to decrease the degree of misalignment between the pin end and the disk counterface. This was achieved by separate alignment of both pin and disk.

On eddy currents in a rotating disk [PDF]

Electrical Engineering, 1942
A DEVICE which often occurs in electric machines and instruments consists of a relatively thin conducting disk rotating between the pole pieces of a permanent magnet or electromagnet. The author has received inquiries as to the method of calculating the paths of the eddy currents and the torque in such cases.

On Relativistic Theory of Rotating Disk [PDF]

Progress of Theoretical Physics, 1952
(II) The problem of dejillillg the uniform rotation of the disk This problem has been investigated by generalizing relativistically some characteristic properties concerning the rotation of classical rigid body or incompressible fluid. In connection with this pro­ blem the law of velocity distribution of uniformly rotating disk is especially important.
