Ion-selective membranes can be used in lab-on-a-chip devices for various portable applications in this field. These devices can be used as concentrators for analytical chemistry and for micro-scale filtration. Here, a binary aqueous electrolyte solution in a microchannel has a potential bias applied across it and it is driven through an ion-selective membrane. Ion concentration gradients form ...

The purpose of this work is to investigate the triggering behaviour of safety fuses for mobile on board supply systems. The influence of different materials and shapes of the fuses on the triggering behaviour are analyzed. Furthermore, the simulation results obtained by the use of COMSOL Multiphysics® are compared to experimentally achieved data. For the transient simulation of the heat ...

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import “realistic structures” from geologic samples scanned by means of computer tomography (CT) as stl-files into COMSOL ...

Erodible polymeric scaffolds can mitigate long-term risks associated with permanent implants currently used to treat ischemic artery disease. However, safe deployment of erodible scaffolds is predicated on understanding the interactions between evolved material by-products and local biological tissues. We developed an integrated computational model of polymeric scaffold degradation, by ...

The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground cavities. In order to accurately perform these multiphysics modelings at high space and time scales, it is ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 µm. Such optical sensors include a detector, typically a micro-bolometer, an IR source ...

HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for fulfilling these roles and continuing with the project until its production phase. The simulation is built with very ...

In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation of pumping performance as consequence of the variation of the chamber-diaphragm system geometry, diaphragm ...

Micro-tubular Solid Oxide Fuel Cells (mSOFC) are attracting more and more interest as new generation of energy conversion devices. Although commercial applications still suffer from high costs, there is a need for further improvement of the cell performance, durability and start-up. To resolve those challenges, knowledge of the distributions of species concentration, temperature and current ...
