    Diesel engines are internal combustion engines with auto-ignition of fuel spray atomization, and the control of fuel injection/fuel spray has a significant impact on the combustion process. Numerous optical measurements and numerical simulations of fuel sprays have been carried out. In spray simulation, breakup models are commonly used for the spray atomization process from the viewpoint of computational load. Numerical simulation of fuel sprays is heavily influenced by the breakup model. The model constants need to be adjusted based on the experimental conditions, such as nozzles used, injection pressure, ambient density and fuel, as well as computational settings, such as mesh size. Visualizing fuel sprays is crucial for adjusting the constants, but it increases worker efforts and man-hours in the development process for Diesel engine combustion research. The purpose of this study is to develop a simulation method which required no adjustment and small computational load. This study conducted simulations of spray atomization and dispersion using breakup models for Diesel sprays. To simulate the primary breakup process, the ITD (: Internal turbulence decay) model was used, and the MITAB (: Modified improved Taylor analogy breakup) model was used as the secondary breakup model. Results using the other breakup models, spray tip penetration by scattered light and droplet size distribution by SHSRP(: Super high spatial resolution photography) were evaluated. It was shown that the ITD and MITAB models are highly applicable and useful for general applications due to their high prediction accuracy and low dependence on mesh sizes.

    <p>There are many spray types for applications, such as internal combustion engines, agriculture, and spray coating. In internal combustion engines, the fuel injection system plays an important role in efficient fuel supply. A systematic approach for understanding the spray formation process requires consideration of differences in injection modes and atomization mechanisms. This research aims toclarify the spray structure for several kinds of engine conditions, such as injector specifications andinjection conditions. In this paper, a prediction model of spray tip penetration is proposed for the spray injected from hole nozzles in several kinds of engine injectors. The spray droplets' velocity and internal gas flow velocity of the spray are also estimated. The prediction model of spray tip penetration considers the atomization and spray-droplet momentum exchange. The analysis results were compared with experimental measurements, which were breakup length, spray tip penetration, and the droplet velocity. The prediction method provided a time-series variation; the errors of spray tip penetration at 1.0 ms after the start of injection were 10.8&amp;#37; for port fuel injection (PFI), 3.0&amp;#37; for direct injection spark ignition (DISI), and 1.5&amp;#37; for diesel condition. Using this proposed model, the features of spray development and the structure for each engine condition were discussed. The time exponential value was nearly 1.0 at the PFI, which is different from the DISI and diesel conditions. The time delay, which for the internal gas flow velocity equals the droplet velocity in the spray, was the dominant factor for the spray structure, and there is a difference between diesel, DISI, and PFI sprays.</p>
