研究方向

多相流检测、计算流体力学模拟、反应器工程

科研经历

1. 博士研究生期间从事密相流化床流场特性与流动结构的研究,从脉动信号数值模拟和多尺度解析的角度出发,建立了流场间歇性、颗粒涡和相干结构的表征方法,发现颗粒涡对密相流化床的间歇性特质起主导作用,相关成果连续3次发表于Chem. Eng. Sci.。同时,参与开发多温区流化床聚乙烯新工艺(气液法),应用于天津石化14万吨/年聚乙烯装置并取得成功,相关成果获授权专利3项。
2. 在浙江大学从事博士后研究期间,以人工肝支持治疗系统的灌流故障问题为背景,采用虚拟区域法—双重直接数值模拟的并行化算法,预测并优化了人工肝流化床生物反应器的性能,发现基于优化策略操作的漏斗型反应器能够有效克服传统反应器的灌流缺陷,提高外源性肝细胞与病人血液的物质交换效率,相关成果发表于Particuology。
3. 在肯特大学从事博士后研究期间,基于静电、振动、颗粒速度脉动信号与颗粒运动的关系,建立了循环流化床中颗粒絮团拟序行为的非侵入表征方法,辨识并描述了颗粒絮团的演化过程及其对流场复杂度与能量再分布的作用机制,相关成果发表于Meas. Sci. Technol., Ind. Eng. Chem. Res., Chem. Eng. J.和Powder Technol.。
