Predicting How Long Coffee Stays Warm in a Vacuum Flask

Fanny Littmarck October 26, 2017

Important question: If you pour hot coffee into a vacuum flask, how long will it stay warm? There are two different modeling approaches for studying this scenario, but the more accurate method is also more computationally expensive. Let’s see what they are and when they are appropriate — and hopefully find an answer to the question.

If an inkjet printhead nozzle is poorly designed, it will lead to a low-quality end product — whether it’s used in a 2D or 3D printer, the fabrication of an integrated circuit, or even DNA synthesis. With simulation, you can determine the ideal printhead nozzle dimensions to achieve precise material deposition. And with the COMSOL Multiphysics® simulation software, you can save time by turning your model into an app for use by other project stakeholders.

Healthcare-associated infections (HAI) affect millions of people around the globe. While the most common cause of HAI is direct contact with the source, airborne bacteria may also play a role in patient infections. To prevent airborne infection and make hospital clean rooms safer, it’s important to design efficient ventilation systems. As an added benefit, efficient ventilation designs also lead to lower energy-related costs. The first step to a better design is CFD modeling.

Erwin Schrödinger is the man behind the famous Schrödinger wave equation that is used to predict the future behavior of a dynamic system in quantum mechanics. Today would have been Schrödinger’s birthday, had he still been alive. Let’s celebrate his birthday with a look at some of his accomplishments.

COMSOL Multiphysics version 5.1 introduces a new tutorial model of a UHF RFID tag. RFID tags allow you to identify and monitor both inanimate objects and living creatures through the use of electromagnetic fields. The UHF RFID tag has a wider range than other types of RFID tags and is often used to identify animals. We can evaluate the performance of the tag through an analysis of the electric field and far-field radiation pattern.

Previous work on cloaking for flexural waves in elastic plates presented limitations and near invisibility. Now, a research group in Europe has figured out a new theoretical framework to both overcome the limitations and achieve exact cloaking for flexural waves in Kirchhoff-Love plates. To visualize and test the quality of the cloak, they ran COMSOL Multiphysics simulations.
