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 …

Mesoscale drag modeling is the critical issue for the simulation of gas–solid two-phase
flows. This article reviews the physical origin of the drag force and the development of …

In this article, we demonstrate the use of artificial neural networks as optimal maps which are
utilized for convolution and deconvolution of coarse-grained fields to account for sub-grid …

Filtered two-fluid model (fTFM) for gas-particle flows require closures for the sub-filter scale
corrections to interphase drag force and stresses, the former being more significant. In this …

In this work, we present a rigorous derivation of the volume-filtered viscous compressible
Navier–Stokes equations for disperse two-phase flows. Compared to incompressible flows …

Simulations of large-scale gas-particle flows using coarse meshes and the filtered two-fluid
model approach depend critically on the constitutive model that accounts for the effects of …

Developing, verifying and validating sub-grid methods is of crucial significance for enabling
accurate coarse-grained two-fluid modeling of rapid gas-fluidized flows. However, very few …

Over the past decade, filtered Two Fluid Models (fTFMs) have emerged as a promising
approach for enabling fluidized bed simulations at industrially relevant scales. In these …

We present an anisotropic, dynamic multi-phase turbulence model for moderately dense gas-
particle flows by spatially averaging the kinetic-theory based two-fluid model …

Abstract Filtered Two Fluid Models (fTFMs) aim to enable accurate industrial-scale
simulations of fluidized beds by means of closures accounting for the effects of bubbles and …
