研究领域和兴趣
发动机喷雾与燃烧
主要业绩
研究方向主要集中在发动机条件下喷雾破碎和相变过程的建模、喷雾与壁面的相互作用建模、喷雾中的超临界转变机制以及电动机的喷雾冷却。构建了适用于发动机相关条件下的飞溅、壁膜形成、壁膜动力学和蒸发以及膜分离的改进模型。此外,提出了高准确性和高效性的多组分准一维蒸发模型,适用于实际多组分燃料的壁膜和自由液滴。在博士后阶段,为IFPEN的CONVERGE软件开发新的多相流模型,进行了与电动机冷却相关的研究,并在氨直喷测试和闪蒸汽化建模方面取得了不错的成果,对减少污染物排放和增加内燃机中碳中性燃料的使用的先进技术发展产生了重大影响。此外,还通过使用数值方法采用多种策略,研究了先进的低温燃烧模式(GCI、RCCI、DDFS等等),以追求超高热效率并实现接近零的发动机排放。
