Summary:

In this work, experimental and numerical study was performed to investigate the macroscopic spray structure and the spray characteristics of common rail type high-pressure injector with multi-hole. The global spray structure and microscopic characteristics of high-pressure diesel injector were investigated at various injection and ambient pressures. Spray developing process and spray tip penetration were obtained by spray visualization system, and the quantitative spray characteristics such as local Sauter mean diameter were measured by using phase Doppler particle analyzer. The numerical study was conducted to analyze the atomization characteristics of common-rail type injector at the same conditions with the experiment. In order to improve the prediction accuracy, the numerical analysis was modified using the hybrid breakup model that is composed of primary breakup and secondary breakup
