Drag force models are one of the most important factors that can affect TFM and CFD-DEM
simulation results of two-phase systems. This article investigates the accuracies …

To study flow dynamics in a fixed‐bed reactor, experiment and numerical simulation are
used. In this work, the flow dynamics in a fixed‐bed reactor filled with porous particles was …

The scientific interest in the efficiency of packed bed columns is a part of the world-wide
pursuit of sustainability of the processes. The maldistribution of the phases in the apparatus …

This study demonstrates the use of computational fluid dynamics (CFD) to evaluate the
hydraulic properties of a new/complicated random packing structure, including flooding …

The work focuses on mimicking the loading of the catalyst pellets into a reactor in a realistic
manner and proposing a simple method to predict catalyst bed density using Blender 3D …

A novel approach is presented that supports the development of new packing types for
absorption processes by “virtual experiments”. Based on a hydrodynamic analogy model for …

Catalytic fixed-bed reactors are the working horse of the chemical industry and optimal
reactor operation is vital in many aspects, such as product quality and profit as well as …

In this work, we investigate particle deposition efficiency in porous media by way of pore-
scale computational fluid dynamics simulations. First, we show how to employ a novel …
