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 …

Most multiphase chemical reactors are complex systems. This paper explores the multiscale
nature of complex systems in chemical engineering and the intrinsic mechanism of the scale …

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

This review covers the scope of multiscale computational fluid dynamics (CFD), laying the
framework for studying hydrodynamics with and without chemical reactions in single and …

Most natural resources are processed as particle-fluid multiphase systems in chemical,
mineral and material industries, therefore, discrete particles methods (DPM) are reasonable …

Multiscale simulation is an emerging scientific field that spans many disciplines, including
physics, chemistry, mathematics, statistics, chemical engineering, mechanical engineering …

Multi-scale spatio-temporal structures, the dominant feature for all complex systems, are
identified and discussed as a common challenge and frontier in process engineering, as …

Despite its wide applications, fluidization is not understood enough to satisfy our technical or
academic interests. Cascading simulation approaches on different scales, with small-scale …

Due to significant multi-scale heterogeneity, understanding sub-grid structures is critical to
effective continuum-based description of gas–solid flow. However, it is challenging for both …

With the dramatic development of computational science and technology, computer
simulation is playing an increasingly important role in scientific research and engineering …
