Particle-fluid system is one of the most popular systems in chemical processes. Owing to complex interface structure and high-velocity turbulence, the momentum and mass transfer exhibit nonlinear characteristics, which pose a great challenge for further study and application. To solve this problem, computational mass transfer (CMT) emerged and has been proved to be effective in deeply exploring the mass transfer behavior of particle-fluid systems. First, this paper reviews recent gas-solid numerical studies of turbulence issues from empirical to theoretical, then discusses interphase mass transfer rate models and the interfacial interaction force. Second, the present study particularly reviews researches on mass transfer process of fixed and fluidized regime by CMT, providing reliable analysis of turbulent anisotropy diffusivity as well as multiscale structure and presenting theoretical instruction for the industrial optimization of mass transfer processes in chemical engineering.

计算传质模拟气固体系多尺度传质过程研究进展

颗粒-流体系统是化学过程中最流行的系统之一。由于复杂的界面结构和高速湍流，动量和质量传递表现出非线性特征，这给进一步的研究和应用带来了巨大的挑战。为了解决这个问题，计算传质（CMT）应运而生，并被证明可以有效地深入探索颗粒-流体系统的传质行为。首先，本文从经验到理论回顾了最近对湍流问题的气固数值研究，然后讨论了相间传质速率模型和界面相互作用力。其次，本研究重点回顾了CMT对固定流态和流态流态传质过程的研究，为湍流各向异性扩散率和多尺度结构提供了可靠的分析，为化工传质过程的工业优化提供了理论指导。
