Predict the Performance of Rotating Cone Micropumps with Simulation
Researchers from Texas A&M University used multiphysics simulation to evaluate the fluid dynamics and performance of a rotating cone micropump, a key component in many types of process equipment.
Understand Phenomena in the Viscous Catenary Problem via Simulation
The viscous catenary problem is theoretically and experimentally significant in many industries due to the complex phenomena it entails. Simulation can help us understand this problem.
Preventing Bubble Entrapment in Microfluidic Devices Using Simulation
Microfluidic devices are no match for bubbles. In fact, if bubbles become trapped in a microfluidic device, it could malfunction. Veryst Engineering created a CFD model to study this process.
Keynote Video: Solving 2 Transport Process Problems with Simulation
In a keynote presentation from the COMSOL Conference 2016 Boston, Carl Meinhart from the University of California, Santa Barbara and Numerical Design discusses simulating transport processes.
Designing Inkjet Printheads for Precise Material Deposition
The design of an inkjet printhead nozzle is important in order for the device to have precise material deposition, whether it is used in a 2D or 3D printer.
Designing Effective Transdermal Drug Delivery Patches with Simulation
Transdermal drug delivery (TDD) patches continuously deliver drugs into the body for a certain amount of time. However, the skin is designed to keep out foreign substances, like drugs. To create a TDD patch that successfully bypasses this barrier, simulation can be used to study drug release and absorption into the skin. To analyze this process, Veryst Engineering created a TDD patch model with the COMSOL Multiphysics® software and compared the results to experimental data.
Evaluating an Insulin Micropump Design for Treating Diabetes
In any form of treatment, it is always desirable to minimize the level of discomfort that the treatment process causes patients, while ensuring overall safety and effectiveness. For diabetes patients, insulin injections remain an important form of treatment, but the process itself can be painful. With the help of multiphysics simulation, a team of researchers from the University of Ontario Institute of Technology sought to develop a MEMS-based micropump that could administer insulin injections in a safe and painless way.
Model How the Bubbles in a Glass of Stout Beer Sink, Not Rise
When you think of a stout beer, one type that may come to mind is Guinness® beer. This stout is very special, noticeable by its dark body and famous white head. The dynamics of the foam alone are interesting enough to write a series of blog posts about. Although I don’t drink Guinness® beer (I’m a fan of IPA), I found the longstanding debate about whether its bubbles are rising or sinking while the beer settles makes an interesting simulation.
