Simulation-Based Sensitivity Analysis of the Direct Ammonia Fuel Cell Operating Conditions
Ammonia is studied both as a hydrogen carrier and as a fuel for renewable energy infrastructure. An important advantage of ammonia compared to carbon-based fuels is that it can be oxidized without greenhouse gas emissions, producing only N2 and water. Direct ammonia fuel cells (DAFCs) ... Read More
Modelling of Desaturation/Resaturation of Geological Repository Barriers Considering Gas Generation
Geological repository for highly radioactive waste disposal is a system of engineered and natural barriers. The objective of this system is to contain and isolate waste and protect the environment and humans from ionizing radiation. For the evaluation of performance of engineered ... Read More
Reinforcement Bars Corrosion in a Carbonated Concrete
In the construction sector, the concrete and the steel bars represent still the key components, although they are very vulnerable by the atmospheric agents, as in the case of their degradation caused by corrosion. The value of the concrete carbonation may enhance the corrosion around the ... Read More
Modelling of Interfacial Charges and Kinetics of Dye-Sensitized Solar Cells Photoanodes
In this study, we attempted to develop a simulation to better understand the kinetic of the dye regeneration process in photoanodes of dye-sensitized solar cells (DSSCs). For that purpose, a numerical model was developed using finite element simulation in COMSOL Multiphysics®. The ... Read More
Thermal Conduction in Anisotropic Granular Mixtures
With the ongoing electrification of vehicles as well as rapid digitalization, thermal management is on everyone´s lips. This includes the use of ever-better materials, specifically tailored regarding their thermal properties. To fine-tune the thermal conductivity of a material, composite ... Read More
3-D Modeling of Light, Flow, Mass and Heat Transfer in Coral Colonies
Corals are symbiotic marine organisms greatly dependent on the dynamic gradients of light, temperature and chemical species, all affected by the water flow in their surroundings. We developed a multiphysics modelling approach to simulate the microscale spatial distribution of light, ... Read More
2-D Ion Transport Modelling of Water Desalination by RO System Considering the Real Membrane Effect
Modern composite membranes for reverse osmosis (RO) and nanofiltration (NF) have an ultrathin polyamide active layer (~100 nm) that performs the ion separation. Current theoretical models explain solute and water fluxes by computing concentration and potential gradients developed in one ... Read More
A Multiscale Approach to Simulate Vacuum Drying of a Packed Bed of Spray-Frozen Particles
Preservation of biopharmaceuticals by spray freeze-drying is of great interest as it involves gentle drying and can be easily integrated with continuous manufacturing strategies. The drying of packed beds have been extensively studied experimentally, but a detailed mathematical model of ... Read More
Proton Enrichment and Surface Charge Dynamics in pH-Responsive Nanopores
The acid-disassociation of surface groups generates the surface charge that drives fundamental nanoscale ion transport behaviors, such as ion current rectification in nanopores. Ion current rectification can be utilized for high sensitivity label-free sensors. The disassociation of ... Read More
Beyond the limits of mass transfer: How pillar electrodes influence electrochemical reactors
Electrochemistry is inherent a surface process, requiring the transport of reagents towards the electrode surface. In electrochemical reactors this typically results in mass transfer limitation problems, limiting the yield and efficiency of the reactor. While the academic community is ... Read More
