MEASUREMENT OF BREAKUP LENGTH OF CYLINDRICAL LIQUID JETS. APPLICATION TO LOW-PRESSURE CAR INJECTOR
Краткое описание
The present article reports an experimental investigation on the characterization of the atomization of plain cylindrical liquid jets. The main objective of the work is to measure the stability curve of jets produced by two different injectors, one of them being dedicated to low-pressure fuel-port-injected engines. Furthermore, in order to investigate the influence of the liquid, three different liquids have been tested. The experimental technique used here was developed in a previous investigation and allows one to obtain jet breakup lengths averaged from 1000 measurements for each situation. The results are therefore regarded as very accurate and reliable. It is found that the stability curve of a liquid jet contains useful information as far as the atomization of the liquid system is concerned. Confirming results obtained in a previous study, it is found here that according to the fluid used, the jet produced by an injector can show different behavior that affects its breakup length as well as the sensitivity of this length to the ambient condition. In applications such as in low-pressure gasoline injection, such information may be very valuable for development of an injection strategy.
