1½-Way CFD-DEM Coupling with DNSlab: 3D Simulation of Microscale Fuid-Particle Processes including Filter Cake Restructuring, Detachment and Re-Entrainment of Deposited Particles

By simulation, filtration processes and filter media can be analyzed, designed and optimized. The more precise the simulation reproduces the real process, the more predictive and meaningful are the simulation results.

1½-Way CFD-DEM Coupling is a new feature of DNSlab which allows to simulate microscale filtration processes including filter cake restructuring, detachment and re-entrainment of deposited particles. The method combines a high modeling depth with a low demand of computation resources. The consideration of detachment and re-entrainment effects is necessary in particular to model solid-liquid-separation processes, where higher viscous forces cause an increased occurrence of these effects.

As an example, Fig. 1 shows the simulated particle distribution in a microfiber nonwoven before (left) and after (right) backwashing, with a reduced particle load after backwashing caused by particle detachment.Fig. 2 shows the particle volume before and after backwashing as a function of the depth in the filter medium.

Validation of the simulation of continuous aerosol deposition at various wire mesh types including non-trivial particle-particle and particle-wire adhesion forces by laboratory measurements

Conference Session: G04 - Particle-Collector-Interaction - 2023-02-14 - 16:45

Simulation of fluid flow and particle deposition with 3D computer models of the pore structure of filter media is a tool for rapid cost-efficient layout of filter media for industrial filter applications, and moreover for improvement of the scientific understanding of filter processes and the involved material systems.

To obtain reliable simulation results which reproduce the real behavior precisely, the simulation must be validated under well-defined laboratory conditions. The validation usually consists of the comparison of pressure drops, filtration efficiencies, deposited particle masses and/or filter cake heights. If the comparison of simulation and measurement results shows considerable deviations, the physical models and numerical implementation of the simulation must be revised, and also measurement errors must be considered.
The aim of this work is to validate the simulation of continuous aerosol deposition at wire meshes, where non-trivial adhesion forces occur between particles and particles and between particles and wires, with it4e’s simulation software DNSlab®...
