A Study on Optimization of Diesel Combustion in condition of Premixed Natural gas

천연가스 예혼합 분위기 내 디젤 연소의 최적화에 관한 연구

This numerical study was carried out to optimize dual fuel combustion on natural gas-diesel in static chamber. Spray experiments conducted under conditions of premixed methan 0%, 5% and 10%. In the results, penetration decreases when premixed methane is increasing. Constants of numerical models were acquired from results of spray experiments to enhance accuracy of numerical study. And dual fuel engine simulation was implemented by using AVL-FIRE with acquired constants.
