Theoretical and Experimental Analysis of Diesel Sprays behavior from Multiple Injections Common Rail System 2002-01-2777

The present work deals with the study of the dynamic behavior of a commercial injector subject to multiple injection strategy. The global spray characteristics have been investigate as well. These studies have been carried out using two numerical codes opportunely modified in order to better simulate the injection process. Comparisons between simulation results and experimental investigations have been made in order to test the reliability of the models. This paper aims at characterizing the macro and microscopic behavior of high pressure Diesel sprays generated by a common rail injector. If it is possible, purpose of this research is to validate and to extend the different correlations available in literature to the case of sprays generated by common rail injectors, especially at high injection pressures.
