Reference: F1R-ING-PUL-08BIFU

Project Leader: Bernhard Peters

Research Team: Suresh Kumar Kannan (PhD),

Research Domain: Engineering/ Fluid dynamics

Project Period: 2008-2011

Partners: Prof. U. Müller, (Karlsruhe) , Dr. Bizhan Bifrui (Delphi Automotive Systems, Luxembourg )

Abstract:

A linear and non linear stability analysis will be performed to investigate the breakup of liquid sheets as applicable to the injector nozzle of a Gasoline Direct Ignition (GDI) engine. The various parameters affecting the breakup of the liquid sheet in to droplets will be identified and compared with experimental results and theoretical results. A Computational Fluid Dynamics (CFD) analysis of the liquid sheet breakup will also performed using the OpenFOAM code based on VOF-LES method. The results of the stability analysis and experimental results will be used to justify the CFD LES model and the drawbacks of the VOF-LES model will be identified. This study is aimed towards the improvement of the design of the fuel injection nozzles used in GDI engines.
