The effect of transient needle lift on the internal flow and near-nozzle spray characteristics for modern GDI systems investigated by high-speed X-ray imaging

Autor: Jin Wang, Tobias Knorsch, Philipp Rogler, Michael Wensing, Dmitrii Mamaikin

Publikováno v: International Journal of Engine Research. 23:300-318

The development of the injector nozzle is a dynamic area in regard of several technical aspects. At first, the internal flow influences the near-field spray characteristics via various phenomena such as cavitation and turbulence. However, these pheno

Abstract Gasoline direct injection engines are highly dependent on the spray performance and associated combustion quality. The spray formation depends on many factors, namely internal flow characteristics, injection conditions, ambient conditions an

Dual-plane stereo-astigmatism: a novel method to determine the full velocity gradient tensor in planar domain

Autor: Nils Herbert Kling, Jochen Kriegseis, Philipp Rogler, Lars Opfer

Publikováno v: Measurement Science and Technology. 31:085202

A novel approach, which utilizes astigmatism-based depth codification and discrete dual-plane illumination, is developed to provide quasi-volumetric velocimetry (2.5D3C) by means of Stereo-PIV. The technique is referred as Dual-Plane Stereo-Astigmati
