Abstract:
Volume-of-fluid large-eddy-simulations (VOF-LES) and optical imaging results of the primary breakup of a pulsed planar-sheet liquid jet are presented and compared. The planar-sheet thickness pertains to the GDI outward-opening conical-sheet spray. The investigations include injection conditions of 0.5 and 1 MPa fuel pressure and 0.3 MPa ambient pressure. The objective of the study is to assess the predictive accuracy of the VOF-LES method for analysis of the Kelvin-Helmholtz (KH) instability and the primary breakup of a transient, pulsed, liquid sheet jet, through inclusion of the injector nozzle flow domain into the simulations. Thus, the simulations do not resort to prescription of the issuing liquid jet velocity boundary condition. The results show good qualitative and quantitative accuracy for prediction of the KH interface instability waves and the liquid-sheet breakup process for the conditions studied.
