기하학적 구조에 따른 압력식 스월노즐의 내부유동 해석 = An Analysis of Internal Flow on the Nozzle Geometry in Pressure Swirl Atomizer

다국어 초록 (Multilingual Abstract)

The swirl atomizer is widely used in domestic and industrial combustion systems. However, the information of the flow characteristics is not enough to design nozzles and to predict the spray characteristics. The velocity profiles at the exit is one of the most important factors to determine the spray characteristics. In this paper, a numerical analysis was made to investigate whether the nozzle geometry influences on the velocity profiles at the exit and the spray angle was calculated with the velocity profiles at the orifice. It was concluded that the geometrical properties of the nozzle were the most influential parameters to determine the flow characteristics and the calculated spray angles show good agreement to a set of measured spray angles.<br/>
