Multiphysics Modeling of Electrochemical Conversion of Potassium Bicarbonate in Porous Electrode Flow Cell

Climate change is a pressing global crisis with far-reaching consequences, demanding the rapid advancement of clean energy technologies and effective carbon capture methods to mitigate Carbon Dioxide (CO₂) emissions. Carbon capture technologies offer a crucial pathway for capturing, storing, and reusing CO₂, thus...

Accelerated corrosion test simulation: Lattice model vs. continuum model

A series of accelerated corrosion tests were done by SGS INTRON (commenced by Combinatie Aanpak Maastunnel, constructor of the Maastunnel project) to investigate for a proper repair material for the deteriorated concrete floor in the Maastunnel at Rotterdam. Five types of fiber reinforced mixtures with different tensile behavior ranging from...

Macroscopic modelling of self-healing thermoset materials

The present contribution introduces a phenomenological model for self-healing polymers. Self-healing polymers are a promising class of materials which mimic nature by its capability to autonomously heal micro-cracks. Self-healing in the here considered system is accomplished by integrating microcapsules filled with a healing agent and a...

On the continuum modelling of segregation of granular mixtures during Hopper emptying in core flow mode

Many industrial processes involve particulates with materials ranging from pharmaceuticals, ceramics, cosmetics and foods. Common to all these particulate processes is the discharge of granular material from bins/hoppers in either mass flow mode (i.e. all material regions in the domain are in motion) or core flow mode (i.e. there is a flowing...
