[論文] 연료분사노즐의 니들밸브 형상변화에 따른 분무특성에 관한 연구

다국어 초록 (Multilingual Abstract)

The experimental study, using constant pressure injection system, is carried out to inves­tigate the effect of the geometrical shape changes of the needle valve on the effective flow area, the spray angle and the Sauter's Mean Diameter according to needle valve lift for a pintle-type injection nozzle.<br/>
The results are as follows:<br/>
1) With the increase of the needle valve lift, the effective flow area is increased, the spray angle is at first increased and later decreased, and the sauter's Mean Diameter is decreased.<br/>
2) It is also shown that the spray angle is maximum at the rapidly increased region of the effective flow area.
