TL;DR: In this article, the energy-minimization multi-scale (EMMS) approach is adapted for investigating the dependence of drag coefficient on structure parameters, and the structure-dependent drag coefficients calculated from the EMMS approach are then incorporated into the two-fluid model to simulate the behavior of concurrent-up gas-solid flow in a riser.

TL;DR: Preliminary efforts on developing and optimizing applications on the TaihuLight system are reported, focusing on key application domains, such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation.

TL;DR: In this paper, a doubly stochastic Poisson process is used to analyze the fluctuation characteristics of solid concentration in CFB risers, which provides a mean to define the solid concentration inside clusters.

TL;DR: In this paper, a drag model based on the energy minimization multiscale (EMMS) approach was proposed to simulate the gas-solid flow in a circulating fluidized-bed riser.

TL;DR: The strategy of "from the particular to the general" in developing the variational multi-scale methodology is emphasized, and challenges for mathematicians and physicists are identified to show the necessity of transdisciplinary cooperations.
