Using the Application Builder as a Tool for Teaching Students

May 19, 2016

Maximizing the efficiency of the learning process while keeping students engaged is the common goal that professors hope to achieve in any course. In the realm of physics- and engineering-based courses, simulation apps are helping to strike such a balance by introducing students to complex concepts in a simplified format. Here, we’ll take a look at some of the innovative ways that university professors are utilizing apps within the classroom.

Studying Manifold Microchannel Heat Sinks with Simulation

May 16, 2016

When an electronic device overheats, it risks starting a fire. Cooling components, such as heat sinks, are designed to prevent this, but can’t always keep up with advancing technology. Simulation offers a solution by illustrating how well various heat sink designs conduct heat and how adding elements like manifold microchannels (MMC) improves performance. Today, we’ll explore how an MMC heat sink operates with simulation.

Simulating a 3D Multilayered Graphene Biosensor Design

May 2, 2016

Graphene is a material with a strong presence — and impact — throughout the scientific community. Amongst its many uses, researchers are looking to graphene as a potential material solution within sensor designs for medical and biosensing applications. Today, we’ll explore the role of simulation in analyzing and optimizing a 3D multilayered graphene biosensor.

Evaluate Characteristics of a Periodic Finned Pipe with an App

April 11, 2016

Radiators, refrigerators, and geothermal pumps all need to efficiently extract heat from one fluid to another without mixing them. Among all of the different heat exchanger designs, finned pipes aim to increase the exchange surface between the content of a pipe and the exterior using fins. Finned pipes usually show a geometrical periodicity along the length, which we will take advantage of in this demo app to reduce computational costs.

Making a Recipe for the Perfect Soft-Boiled Egg with Simulation

March 31, 2016

Two professional chefs stand in a classroom, closely observing a soft-boiled egg. What may initially sound like a cooking class is actually part of a physics course offered at the Technische Universiteit Eindhoven (TU/e) in the Netherlands. Using COMSOL Multiphysics, students are investigating the science behind cooking the perfect soft-boiled egg. See how this innovative blend of simulation research and food science is teaching students how to build and test models.

Modeling Thermal Ablation for Material Removal

March 30, 2016

Whenever solid materials are heated enough, they will melt and then vaporize to a gas. Certain materials will even go directly from the solid to the gas phase, a process referred to as sublimation or ablation. If the material is heated strongly enough, there will be significant material removal. Today, we will look at how you can model this process in COMSOL Multiphysics.

Studying Transient Heat Transfer in a Fin Design with an App

February 29, 2016

Continuing his discussion of simulation apps, guest blogger Mehrzad Tabatabaian presents an app that he designed to study transient heat transfer in a nonprismatic fin. In earlier blog post, I spoke about my new book, COMSOL5 for Engineers, a resource designed to inspire and guide the creation of COMSOL models and simulation apps. Today, I’ll share a model with you that I created to analyze transient heat transfer in a fin as well as its corresponding app.

Design Safe Wearable Technology with Heat Transfer Modeling

February 1, 2016

Year by year, wearable technology grows in popularity for both consumer and medical applications. These devices are meant for continued use, but the heat that they produce could lead to malfunction and burns if not properly designed. To prevent injury to the device user, it’s important to take the effects of heat transfer into account during the design process. The simulation capabilities of COMSOL Multiphysics make this possible.
