A critical comparison of two-fluid model, discrete particle method and direct numerical simulation for modeling dense gas-solid flow of rough spheres
Wei Bian,Xizhong Chen,Junwu Wang +2 more
TL;DR: In this article, Tang et al. compared the results of TFM and DPM simulations with the direct numerical simulation (DNS) and experimental data of Tang et. al. (2016), and showed that the latter model can correctly capture, at least in a qualitative sense, the main hydrodynamic features obtained from DNS, but some TFM simulations with exactly same drag coefficients show anomalous phenomena.

Assessment of the interphase drag coefficients considering the effect of granular temperature or solid concentration fluctuation via comparison of DNS, DPM, TFM and experimental data
Wei Bian,Xizhong Chen,Junwu Wang +2 more
TL;DR: Tang et al. as discussed by the authors showed that the effect of the fluctuation of state variables on the interphase drag force can only have a minor impact on simulation results as compared to the difference caused by using different basic drag correlations; they are insufficient to fill in the gap between DPM/TFM and DNS results; and DPM simulations offer a much better agreement with DNS results, especially when compared with the direct numerical simulations.

Quantifying the non-equilibrium characteristics of heterogeneous gas–solid flow of smooth, inelastic spheres using a computational fluid dynamics–discrete element method
TL;DR: In this article, computational fluid dynamics-discrete element method (CFD-DEM) simulations of bubbling, turbulent and fast fluidization of smooth, inelastic spheres were conducted to systematically analyse the valid range of Navier-Stokes (NS) order continuum theory.
