研究方向
(1)工业过程多相流基础
  多相流反应过程广泛存在于能源、化工、环境、生化等过程工业中,具有复杂的多尺度特征。理解复杂多相流动的结构演化、相间作用以及热质传递规律对过程工艺的设计放大、调控优化具有重要意义。本课题组建立了基于能量最小多尺度方法的双气泡理论模型,阐明了宏观流域过渡的介尺度物理机制。这一理论模型还用于计算流体力学模拟中的相间曳力、气泡/液滴聚并破碎及湍流模型的开发,实现了工艺关键参数的准确模拟,用于工艺优化、过程强化和诊断。针对气固流态化体系,课题组聚焦于工业过程中的颗粒粘结、失流现象的研究,揭示颗粒粘结机制,探究流型转变和异常流态化行为规律,旨在建立颗粒粘结与流态化之间的关联,为流化床的优化调控提供科学指导。在模拟方法方面,致力于发展多相流高精度模拟与并行计算方法,开发LBM-LES等大规模快速并行算法,实现大型工业装置的模拟优化。
