How to Analyze Thermoelectric Cooler Designs with a COMSOL App

Nancy Bannach March 8, 2017

Thermoelectric coolers come in various types and sizes, including single-stage and multistage devices. Their application area is large, as they are used in both consumer products like cooling boxes and as temperature controllers in satellites. If you are looking to analyze the design of a thermoelectric cooler and optimize it for a specific application area, a simulation app is an efficient way to accomplish your goals. We discuss how to use the Thermoelectric Cooler demo app in this blog post.

When modeling a structure with beam elements, we don’t use the actual 3D geometry. Instead, we use a line model, which represents the other two dimensions through defining a set of cross-section properties. With the Beam Section Calculator simulation app, we can easily find the properties for a wide range of beam sections from European and American standards. The app also makes it simple to accurately compute the stress distribution for a given set of applied moments and forces.

Electrochemical impedance spectroscopy is a versatile experimental technique that provides information about an electrochemical cell’s different physical and chemical phenomena. By modeling the physical processes involved, we can constructively interpret the experiment’s results and assess the magnitudes of the physical quantities controlling the cell. We can then turn this model into an app, making electrochemical modeling accessible to more researchers and engineers. Here, we will look at three different ways of analyzing EIS: experiment, model, and simulation app.

Electrical installations must often adhere to requirements for the maximum electric field levels in their surrounding area. Electric fields that are too high can be harmful to both operators and the general public. Simulation is typically used to verify that these levels meet the requirements, otherwise significant redesigns may be needed much later on. The Application Builder enables design engineers to perform verification studies earlier in the process.

Magnetic prospecting is a useful technique for finding iron ore deposits and reducing exploration costs. While simulation provides a way to better understand and improve this process, generating results for each new scenario can be time consuming. Instead, engineers can increase efficiency by designing a magnetic prospecting app for personalized analyses. Here, we discuss an app that quickly generates customized results by enabling users to import heightmaps and geographical data and then add magnetic simulations.

When a pipe springs a leak, it’s important to find its location with a quick and accurate method. Engineers at Echologics — a Mueller Technologies Company — use a combination of acoustic sensors and simulation applications to pinpoint such leaks. Sebastien Perrier of Echologics discussed the benefits of this approach and gave a live demonstration of an acoustics modeling app during his keynote talk at the COMSOL Conference 2016 Boston. If you missed Sebastien’s presentation, you can watch it below.

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.

For patients with renal failure, an efficient dialysis treatment is vital. One point of focus is designing high-performance dialysis equipment that increases contaminant removal, improving treatments like hemodialysis. To accomplish this, you can study aspects of the hemodialysis process, such as membrane dialysis devices, with numerical modeling apps. These apps, like the one discussed here, enable users to more quickly analyze the effects of different inputs and improve designs.

Learning how to use computational tools requires training. This is why a large group of stakeholders — one that continues to grow — relies on a small pool of experts to perform simulation analyses. The Application Builder, part of the COMSOL Multiphysics® software, is helping to bridge this gap. Simulation experts can now wrap models in an easy-to-use interface, making multiphysics simulation more accessible to a wider audience. See what our customers have to say about the Application Builder.

For many years, it’s been possible to analyze synchronized CAD geometries in COMSOL Multiphysics® via the LiveLink™ interfacing products. But did you know that you can also incorporate this functionality into an easy-to-use simulation app? With an app, you can dynamically modify your geometry in a CAD program such as SOLIDWORKS® and use this information to analyze new product designs. Today, we will demonstrate how to do so, using the new Bike Frame Analyzer app as an example.

When designing a perforated well to recover oil and gas, choosing the right number of perforations with the appropriate properties is key. Too many holes and you run the risk of equipment failure or injury; too few and you decrease productivity levels. One way to achieve this balance and improve the safety and productivity of the recovery operation is to model fluid flow near the wells. Let’s see how the Application Builder makes this process even more efficient.
