摘要
在KIVA程序的基础上修改了油滴的蒸发模型,并根据实测数据对溶有CO2的燃油在缸内的喷射、蒸发、燃烧过程进行了数值模拟。计算结果表明,溶有CO2的燃油喷射可有效地降低燃烧初期油束区的温度和氧浓度,从而降低燃烧温度,减少NOx的生成。
In this paper, the KIVA code was modified to simulate the combustion of fuel containing dissolved CO2. The process of flashing boiling injection, evaporation and combustion of fuel containing dissolved CO2 in diesel engine was investigated. Predicted results show that the temperature and oxygen concentration within the spray at the beginning of combustion can be reduced. The mechanism of reduction of NOx emission was discussed. The simulation results were in good agreement with the experimental findings.
