چکیده انگلیسی
It is well known that the electrification of jets of dielectric liquid can totally change the characteristics of the atomization. Due to the presence of electric charges in the liquid the stability of the jet changes and, therefore, mechanisms of creation of the droplets change as well. Moreover since the droplets become charged they repulse each other and disintegrate in a different way from non-charged droplets. In this article, we test the electrification system for aeronautical applications. We present the results of the measurements done on electrified jets of fuel (electrification of the liquid by injection of charges in the injector) with a Malvern system. The mean velocity of the liquid ranges between 40 and 100Â m/s, the applied voltage can vary between 0 and 30Â kV and the ratio L/D (length/diameter) of the injector varies from 10 to 2. The histogram and mean diameter graphs recorded live are given and analysed in terms of the ratio L/D.
