Abstract
Apparatus of rotating disk and cup are widely used spray paintings and industrial boilers. This study was conducted experimentally to investigate the characteristics of liquid atomization in a rotating disk atomizer by means of viscous liquid mixed water and glycerin. The Purpose of this study are to observe breakup mechanism according to the variation of supplied flow rate $0.4{\sim}30 cm^3/s$ and rotating speed $200{\sim}4000rpm$, and to investigate three kinds of breakup Pattern such as drop ligament and film formation by comparing the transition flow rate. ligament number and ligament length to those of Tanasawa and Matsumoto's empirical formula. The results are as follows ; The higher it makes use of viscous liquid. the better it get the characteristics of breakup mechanism. Also When I compared practical value with experiential value at similar test conditions. it was shown similar tendency though were a little variation.
