High Speed Shadowgraphy of Transparent Nozzles as an Evaluation Tool for In-Nozzle Cavitation Behavior of GDI Injectors

Mamaikin, Dmitrii; Knorsch, Tobias; Rogler, Philipp; Leick, Philippe; Wensing, Michael (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Gasoline Direct Injection (GDI) systems have become a rapidly developing technology taking up a considerable and rapidly growing share in the Gasoline Engine market due to the thermodynamic advantages of direct ...
Internal flow and air core dynamics in simplex and spill-return pressure-swirl atomizers

Maly, Milan; Janáčková, Lada; Jedelský, Jan; Sláma, Jaroslav; Sapík, Marcel; Wigley, Graham (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] It is well known that the spray characteristics of pressure-swirl atomizers are strongly linked to the internal flow and that an unstable air core may cause instabilities in the spray. In this paper, a 10:1 scale ...
Study of cavitation phenomenon using different fuels in a transparent nozzle by hydraulic characterization and visualization

Payri, Raul; Salvador Rubio, Francisco Javier; Gimeno, Jaime; Venegas Pereira, Óscar Hernando (Elsevier, 2013-01)

In this paper the behavior of the internal flow under cavitating conditions and the influence of using different fuels is studied. For this purpose, a transparent nozzle (quartz plate) with a cylindrical orifice and four ...
