A Study on the High-Efficiency Atomisation Molten Materials (PART 2 : A Study on the Mechanism of Liquid Supplying and Film Formation by Applying the Ejector Principle)

Atomize법에 의한 용융소재의 고효율 미세화에 관한 연구(제2보 : 이젝터의 원리를 이용한 액체노즐의 액체공급 및 액막생성 기구와 특성)

The negative pressure as much as 10's mmHg is demanded at nozzle inside, in case of atomizing the large density molten materials. by conventional air jet nozzle. In this study, suction type fluid nozzle is designed by applying the ejector principle in order to clarify the air flow of nozzle inside, mechanism of liquid suction and liquid film formation. The results of this experimental study areas follows. Suction force of liquid is magnified by using liquid nozzle, and it is able to supply the liquid stable. Negative pressure at nozzle inside is varied by throttle angle of liquid nozzle, position and outer diameter of air jet nozzle, and have a influence on liquid suction quantity and liquid film formation.
