How can teachers improve student learning in undergraduate science, technology, engineering, and mathematics (STEM) courses? To find out, Ivana Milanovic, a professor at the University of Hartford, developed a simulation-based approach that combines problem-based learning (PBL) and inquiry-based learning (IBL). Milanovic discussed her strategy and its benefits during her keynote talk at the COMSOL Conference 2018 Boston. Below, you can find a summary and video recording of her presentation.

From blood pressure sensors to electronic money cards, planar coils are widely used. Found on circuit boards, these coils are a good choice for inductive coupling, especially when space is limited. When designing these coils, it’s important to calculate both their inductance and resistance, as these factors play a key role in the device’s performance. To do just that, engineers can use layered shell functionality in the COMSOL® software, which enables them to model all coils on one plane.

An air ambulance flies overhead, speeding toward a hospital with a life-saving treatment. This “treatment” isn’t a new medicine or machine but an organ on its way to a patient on a transplant list. To keep the organ at just the right temperature during transport, it’s placed inside a special container called a cold or isothermal box. By using simulation, you can analyze the design of these boxes, making sure that they’re reliable for their life-saving purpose.

When it comes to synchrotron light sources, brighter is better. By using bright beams in their accelerator, researchers at the Advanced Photon Source (APS) synchrotron facility can efficiently gather detailed data. In collaboration with APS engineers, Nicholas Goldring of RadiaSoft LLC creates and distributes simulation applications for designing vacuum chambers relevant to the APS. Below, find a video recording and summary of his keynote talk from the COMSOL Conference 2018 Boston.

Groundwater is an important source of irrigation and drinking water, so keeping it pure is crucial. However, once contaminants get in, it isn’t so easy to get them out — creating systems to remove contaminants from groundwater requires an understanding of the complex way immiscible fluids move through soil. To gain insight into this behavior, engineers can use the phase transport functionality in the COMSOL® software.

A pioneer in chemistry, sanitary engineering, and human ecology, Ellen Swallow Richards paved the way for women in science. She was the first woman to attend, graduate, and teach at MIT. During her career, she developed standards for water quality and isolated the chemical element vanadium. In addition, Richards was passionate about using science to create a better home life, founding the field of home economics.

Ever wonder why the sky is blue? Lord Rayleigh answered this question, explaining that the color comes from the scattering of sunlight off small particles in the atmosphere. A prolific scientist, Rayleigh made notable contributions to a wide range of fields, including optics, acoustics, and fluid flow. He is best known for discovering argon, an accomplishment for which he won the Nobel Prize in Physics.

From tiny cellphone chargers to large-scale generators, transformers are used to increase, decrease, and isolate voltages in all sorts of applications. While these electrical devices have a pretty simple structure, optimizing their performance can be challenging, as it involves accounting for the coupling of magnetic and electric fields, the behavior of ferromagnetic materials, and more. To analyze these effects, engineers designing transformers can use the COMSOL® software.

Schottky diodes are one of the oldest semiconductor components, but they are still found in many modern applications, including computers and radar systems. To ensure that a Schottky diode performs well, it’s important for engineers to accurately analyze factors like current density and barrier height in the design. As a benchmark model demonstrates, the COMSOL Multiphysics® software and add-on Semiconductor Module are well suited for this type of analysis.

If you’ve ever gone on a road trip, you know that it’s a bit of a pain — literally. Part of why your body aches after driving long distances is due to whole body vibration (WBV), which can cause fatigue; motion sickness; and, eventually, serious health problems. To design systems that reduce WBV for cars and other applications, engineers need an efficient way to visualize the effect of vibrations on the human body. That’s where simulation comes in.

Efficient, cost effective, and environmentally friendly, friction stir welding (FSW) is useful for many applications. As the name implies, this process involves using friction to heat materials and then stirring them together. For optimal FSW performance, the generated heat has to be just the right temperature: Too high and the materials melt, weakening the weld; too little and the process is inefficient. Using the COMSOL® software, you can evaluate and improve heat transfer in the FSW process.
