Maximizing the efficiency of the learning process, while keeping students engaged — this 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.

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.

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.

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.

Surely you remember the last time you were stuck in bed with the flu. Influenza, commonly known as the flu, can be at the very least an unpleasant experience, but it also claims a lot of casualties every year. Today, public health officials use mathematical modeling techniques to study the flu and other infectious diseases to predict their spread and make informed decisions about public health.

Lasers, focused beams of photons of a single wavelength, find use in a wide variety of applications today — from noninvasive surgeries and fiber optic communication to material processing and even DVD players. Let’s see how a research team from Lawrence Livermore National Laboratory (LLNL) used the power of multiphysics simulation to investigate laser-material interaction to avoid the damage of optics internal to high-power laser systems.

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.

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.

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.

Radiofrequency tissue ablation is a medical procedure that uses targeted heat for a variety of medical purposes, including killing cancerous cells, shrinking collagen, and alleviating pain. The process involves applying mid- to high-frequency alternating current directly to the tissue, raising the temperature in a focused region near the applicator. We can simulate this process with COMSOL Multiphysics and the AC/DC and Heat Transfer modules. In today’s blog post, we will go over some key concepts for modeling this procedure.
