On The Centrifugal Disk Atomization

General Consideration

Abstract

Some physical interpretation is made in connection with the basic consideration of the flow of liquid on the rotating disk, in order to make clear the method of application of formula given for the determination of maxium drop-size.
To investigate the mechanism of atomization, especially in the determination of the type of dropsize distribution, some assumption is introduced from the view point of surface energy increase in breaking up of the droplet. The result obtained is the type of Pearso's No. 5 distribution. Thus we find we can explain the physical aspect of the type of distribution presented by Tanasawa.
Next the general trend of the method of calculation has been studied in order to determine the trajectory of droplets, Substituting the molecular viscosity of surrounding air for the turbulent viscosity affected by the mutual effect of Karman's voltex, we introduced a basic assumption for the mutual effect of falling droplets. From this inference, we see, the first approach can be made in accordance with the data presented by Marshall and in our own experimental work.
