Abstract

In this paper, we present alternative modeling methodologies for spray simulations which considers the atomization based on fuel properties for RANS based calculations. This new modeling strategy recognizes the fuel properties at the point of atomization to predict the initial droplet size distribution based on correlations in the literature. This distribution depends on both the injector and the fuel properties at the point of atomization. Further, the correlation was modified to obtain an accurate prediction of the spray without using any breakup model by assuming a constant droplet size. This reduces the uncertainty of the breakup model constants on the spray characteristics. The spray characteristics can be well predicted by applying the new modeling strategies and are considerably faster compared to the traditional way. For validation purpose 'ECN spray A' case was used with dodecane as the fuel.
