AltaSim Uses Simulation to Improve Bolometer Sensitivity

June 15, 2016

Bolometers have the ability to detect and measure the power of incident electromagnetic radiation. This allows them to be used in a range of technologies, from night vision cameras to far-reaching astronomy projects. Designing bolometers often requires devoting a lot of time and energy to the development phase, as these devices must be optimized for sensitivity and customized for their specific applications. To efficiently design bolometers with increased sensitivity, AltaSim Technologies utilized the simulation capabilities of COMSOL Multiphysics.

Why Heat Transfer Modeling Can Benefit from Weather Data

June 6, 2016

When designing a device or process, it is important to not only study the system itself, but to also account for the effects of the environment around it. Historical weather data can help to address such effects by offering deeper insight into the weather patterns across different locations and time frames. Take a closer look at how such data can foster better design decisions, with a particular emphasis on its benefits within heat transfer modeling.

Analyze Porous Structures with Numerical Modeling

May 31, 2016

Reservoirs, dams, and other outdoor structures need to be strong, reliable, and sound. The porous materials found within these structures can be easily damaged by pressure changes that cause fluid flow and gradual caving and sinking. Using the multiphysics simulation capabilities of COMSOL Multiphysics and the Poroelasticity interface, we can accurately analyze porous materials to evaluate and avoid deformation in such structures.

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.
