[디젤엔진부문] 디젤분무의 모델링을 위한 혼합 모델의 개발(2) = Development of Hybrid Model for Modeling of Diesel Spray(2)

다국어 초록 (Multilingual Abstract)

In this study, a hybrid model for the prediction of diesel spray breakup is developed. A hybrid model is required to develop by considering the primary and secondary breakup of liquid jet. According to this approach, wave growth and turbulence(WG1) model was used for the primary breakup of the liquid jet and droplet deformation and breakup(DDB) model was used for the secondary breakup of droplet. Development of hybrid model by using KIVA-II code was performed by comparing with the experimental data of spray tip penetration and SMD from the literature.<br/>
A hybrid model developed in this study could give the good agreement with the experimental data of spray tip penetration. The prediction results of SMD were in good agreement the location of 20mm and 30mm from nozzle tip. Hybrid model suggested in this study could give the good agreement with the experimental data with the DDB model constant Ck of 8.0 when Weber number becomes less than 1100.<br/>
