Designing Apps to Thermally Characterize Electronic Devices

Guest Giuseppe Petrone January 18, 2016

Today, guest blogger and Certified Consultant Giuseppe Petrone of BE CAE & Test discusses creating apps to perform thermal analyses of electronic devices. When manufacturing electronic devices, leading companies often look to simulation in order to thermally characterize their products. At BE CAE & Test, we have found a more efficient way of answering such requests: designing apps that are tailored to our customers’ needs. Our surface-mount device app, presented here, is just one testament to what apps can achieve.

Modeling complex geometries with thin structures can be very costly in terms of computational effort, particularly as such structures require quite a lot of mesh elements in order to resolve them. COMSOL Multiphysics provides dedicated features for modeling thin structures so that such models can be solved efficiently while maintaining accuracy. To set up and postprocess thin structures, COMSOL Multiphysics also provides specialized operators to help you consider all the relevant parameters required for accurate results.

Contaminated produce contributes to food waste — a growing problem in the global agricultural industry. Solar dryers are one way to preserve fruits and vegetables, but these devices must be able to function properly to be effective. Heat transfer simulation can be used to analyze solar food dryer designs and identify the right building materials, including phase-change materials (PCMs), which conserve the solar heat. Today, we’ll explore simulation research focused on optimizing a solar dryer design for efficient food preservation.

Studying fish locomotion enables researchers to design vehicles and robots that can skillfully navigate aquatic environments. Performing such studies requires fluid-structure interaction (FSI) analyses of the fish and their environments. Using COMSOL Multiphysics, researchers from the Università Roma Tre were able to simulate carangiform swimming, a type of fish movement, and accurately evaluate its dynamics.

Say you’re riding a bicycle and someone gives you a push from the side. To quickly stabilize yourself, you turn the handlebar of the bicycle in the same direction to counteract the fall. While riders do this instinctively, what’s fascinating is that our bicycles can do the same thing. Modern bicycles are designed to be self stable; they’re good at keeping balance while moving uncontrolled. Let’s take a look at how we can simulate this effect in COMSOL Multiphysics.

Mufflers are used for acoustic soundproofing in combustion engines and HVAC systems. Before achieving optimal performance, a muffler design can go through several iterations. COMSOL Multiphysics provides a flexible environment for testing different designs, saving time and costs while ensuring high performance. Now, with simulation apps, each modification no longer requires the help of a simulation expert. Instead, colleagues can run their own tests and deliver faster results to customers. Our Absorptive Muffler Designer demo app offers insight.

After recently encountering the equations of motion for rotating bodies for the first time, one of my sons came home with a number of interesting questions. His questions brought about a flashback, as I remembered sharing this sense of confusion when studying mechanics many years ago. In today’s blog post, I will present two COMSOL Multiphysics models — one of a gyroscope and one of a spinning top — that illustrate the remarkable properties of rotating bodies.

Reinforced concrete beams are commonly used in modern construction due to their strength and durability. To avoid failure, each new beam design needs to be optimized and tested for safety. Building physical prototypes to test every design modification can be a long and costly endeavor. Simulation apps offer a solution, saving time and money as they bring simulation power into the hands of more people. Explore the benefits of this approach with our Parameterized Concrete Beam demo app.

Microchannels are versatile structures that can be used for thermal management. One way to optimize heat transfer within such systems is by adding a pin fin heat sink to the microchannel configuration. Applying this approach, a team of researchers created a novel pin fin design, analyzing its heat transfer efficiency with COMSOL Multiphysics. They presented their innovative work at the COMSOL Conference 2015 Boston.
