Wind turbine noise is a (hotly disputed) topic that we’ve mentioned on the blog before. While research into noise production by wind farms is still being debated among researchers, one way we’ve found to overcome these noisy turbine troubles is to place turbines offshore where they can’t be heard and, conveniently, high winds with more regularity make energy production more effective. However, a question that comes to mind is: What impact do offshore wind farms have on marine life?

Modernizing the power grid is a huge undertaking. The power industry is mustering up its vast engineering knowledge base to develop the components and systems that will bring us efficient and reliable electrical power for decades to come. By leveraging highly accurate simulation technology with knowledge gained over decades of analyzing in-service equipment, engineers are creating new designs as well as retrofitting proven technology.

High temperatures can be used to destroy tumor cells, a cancer treatment known as hyperthermic oncology. Although the idea behind this treatment method has been around for some time, it wasn’t until recently that new tools and more precise delivery of heat has allowed hyperthermia to be used for cancer treatment. As hyperthermic oncology studies continue, simulation has proven a valuable tool for achieving a deeper understanding of how to deliver heat to tumors while limiting damage to healthy tissue.

Magnetic fields are fundamental forces in the universe. Without them, planetary orbits, electricity, and elementary particles could not exist. Helmholtz coils are used by scientists to generate uniform magnetic fields to study electromagnetism and its characteristics. They are used in MRI, spectroscopy, magnetoresistance measurements, and equipment calibrations. Here, we’ll look at what Helmholtz coils are, why they are important, and how can they be modeled.

When modeling computationally taxing geometries, you can save time by using cyclic symmetry to cut down on memory usage. This can be more complex for rotationally than axially symmetric geometries. However, with the Structural Mechanics Module you can easily solve a single section of an impeller model and still get accurate results.

There are, in general, two different types of ventilation systems: mixing ventilation and displacement ventilation. Displacement ventilation is used in large spaces with tall ceilings (at least three meters high), and therefore is mainly found in office buildings, schools, and other public spaces. These higher ceilings allow for upward convective flows exhausting air contaminants, thus resulting in improved air quality. This post explores the simulation of a displacement ventilation system to determine the air temperature and velocity within a room.

With shrinking electronic devices and ever-increasing power densities, efficient thermal management is at the heart of many R&D activities for electronics engineers. When developing complete systems containing multiple components, designs can become rather complex. An example of such a design would be a computer power supply unit (PSU), which can include not only electronics, but also multiple heat sinks, cooling fans, perforated grilles, and other large components — all within a small enclosure. In this blog post, we will explore […]

Not too long ago, my colleague Jennifer wrote a blog post about the Cross Cancer Institute, and the research being conducted there into the design of a new device for treating cancerous tumors. The device, known as the Linac-MR, is revolutionary due to its ability to both image and treat cancer cells simultaneously — a capability that had previously been regarded as near impossible due to the conflicting physics interactions involved. Such a device would allow for extremely precise radiation […]

A while back, I had the opportunity to speak with Steven Conrad, a critical care physician at the Louisiana State University (LSU) Health Science Center in New Orleans. Not only is Dr. Conrad a physician as well as a professor at LSU, he’s also a biomedical engineer who uses finite element analysis (FEA) to conduct research on the design of dialyzers. Dr. Conrad uses COMSOL Multiphysics to gain a deeper understanding of the physics behind these devices, and to create […]

In the past, we’ve discussed a few of the extraordinary uses of 3D printing (or additive manufacturing) technology by some innovative engineers, and even printed a few of our COMSOL models. In one of our previous posts on 3D printing, we discussed some of the limitations that this technique poses from both a consumer and manufacturing stand-point — you can only print one material at a time. Now however, as was mentioned in an article in Desktop Engineering, not only […]
