• Significant influences of turbulent mass diffusion on mass transfer processes are found.

• Some future directions for developing computational mass transfer based model are pointed out.

Abstract

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.
