Abstract:

An analysis of the applicability of existing diesel fuel spray penetration models to results from the experimental evaluation of the fuel spray penetration of high-pressure diesel spray cases for different injector nozzles is presented. The experimental test conditions include injection pressure values of up to 2000 bar. Of the correlations evaluated, that of Hiroyasu & Arai can be used before the droplet break up time but discrepancies appear after this instance. The results will form part of the basis for the development appropriate correlations for high pressure diesel spray penetration models
