Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

This article reviews the general features of the multiscale structures in particle–fluid systems
and the characterization, modeling, and simulation methods for these systems. The …

Understanding the hydrodynamics of gas–solid flows is a grand challenge in mechanical
and chemical engineering. The continuum-based two-fluid models (TFM) are currently not …

I became engaged in meso-scale research in 1984 when beginning a Ph. D. degree
supervised by Prof. Mooson Kwauk, who believed that the phenomenon of particle …

Gas–solid flows have been numerically investigated by various multiphase models, none of
which is suitable for all the problems encountered in industries. Different multiphase models …

Engineering simulations have opened several gates for today's chemical engineers. They
are powerful tools to provide technical content as physics-based numerical solvers …

Circulating fluidized beds (CFBs) have been widely applied in coal combustion and
gasification industry due to their excellent performance in terms of fuel flexibility and …

MP-PIC (multi-phase particle in cell) method combined with the EMMS (energy minimization
multi-scale) drag force model was implemented with the open source program MFIX to …

Virtual process engineering (VPE) aims to redefine the roadmap for process scaling-up and
optimization, from stepwise experiments to high-performance computer simulations. This is a …

Multiphase chemical reactors with characteristic multiscale structures are intrinsically
discrete at the elemental scale. However, due to the lack of multiscale models and the …
