The Laboratory for Environmental Flow Modeling at the University of California, Riverside, has used ANSYS Fluent software to model a variety of environmental flows. As a third year Ph.D. candidate student in Mechanical Engineering, I recently evaluated the influence of roadside vegetation barriers on the near-road air quality using Computational Fluid Dynamics (CFD), as part of a research team that included my colleague Seyedmorteza Amini and my advisor Dr. Marko Princevac.
Exposure to traffic-related air pollution leads to public health concerns such as respiratory problems, birth and developmental defects, cardiovascular effects and cancer for people who live and work near major roadways. The near-road air quality can be improved directly by deploying vehicle emission control techniques, using alternative fuels or electric vehicles (EVs), or via passive pollutant control and roadside configuration design such as solid and vegetative barriers.

I was recently presented with a unique opportunity to compare the results of full ANSYS CFD simulations with the results obtained using the new ANSYS Discovery Live product, which provides results instantly upon changing the geometry without interrupting a run. I was very pleased and surprised by the speed and accuracy of Discovery Live in this comparison test.
I work for Astec, Inc., the subsidiary of Astec Industries that builds asphalt plants. Roadtec Inc., another Astec Industries company, builds asphalt pavers, reclaimers and material transfer vehicles (MTVs). An MTV helps to accomplish non-stop, non-contact paving by offering a continuous supply of Hot Mix to the paver. By separating dump trucks from the paver this way, contractors are able to make a smoother finished road.
The role of 3-D physics, systems simulation and embedded software is expanding rapidly into new industries and disciplines. A few years ago, 3-D physics simulation was limited to specific departments within organizations, and often these departments did not coordinate with each other on product development activities. Fast forward to today, and much has changed and must continue to evolve in order for companies to remain competitive in the changing landscape of product development. Integrated 3-D physics, systems simulation and embedded software tools are of the utmost importance — especially when tackling the challenges of quickly and accurately developing the technology driving digital twins and autonomous vehicles.
Join us in Paris for our Innovations Conference on December 5-6 and learn how our customers are using simulation to bring their products to market faster.
In the world of stock-car racing, finding even the smallest competitive advantage is the difference between winning and losing.
That’s why at Richard Childress Racing, we design and build our race cars end-to-end. We engineer and machine our own chassis and suspension components, we design and fabricate our own bodies, and we test and build our own engines. Everything is built from the ground up at RCR.
LEDs are increasingly used in automobile headlights because of their small size and reduced energy consumption. But, though they are much more energy efficient than traditional headlights, most of the energy required is converted to heat rather than light — 70 percent, in fact. This presents a challenge to engineers and designers because, since they are semiconductor-based, the diode junction of LEDs must be kept below 120 C. Maintaining temperature below this limit typically involves cooling airflow from an electric fan combined with heat sink fins.
Developing a luxury electric vehicle (EV) from scratch with a short deadline demands organization and access to the right technology to get the job done. Lucid Motors of Menlo Park, California, met the first challenge by putting all the engineers in one room so the structural and aerodynamics engineers would know what the battery, motor and power electronics engineers were doing, right from the start. This collaborative environment has helped them to design a unique automobile with more passenger space by reshaping the battery stack, while optimizing the electric motor, the cooling system, the aerodynamics and the battery life.
All great discoveries and inventions begin with a vision. A vision to make a better product, solve a unique problem or make life easier in some capacity. For centuries scientists and engineers have made tremendous progress in discovering scientific phenomena, or in solving technological challenges. I could write extensively about many of those inventions and discoveries, but there is one I would like to highlight.
In 1928, a Scottish biologist named Alexander Fleming returned to his lab from vacation. As he was sorting through some petri dishes he noticed something unusual. One particular dish had several colonies of bacteria and a cluster of mold. However, there was no bacteria growth near the cluster of mold. Although he did not realize the magnitude of his observation at that moment, he would later be credited with discovering the first lifesaving antibiotic, which he called penicillin.Continue reading →
Every time I travel in Europe, I enjoy riding the fast, comfortable trains. Riding from city center to city center without long security lines and tight uncomfortable airplane seats (worse for me because I’m tall!) can even make travel pleasant. But, I’ve always taken that comfort for granted. Were trains not always that way? Then, I found out about the challenges that Siemens engineers face as they design passenger coaches. Now I have huge respect for those engineers. Read on to find out how CFD is making their lives easier while giving me the comfort I love.
Each year the University of Canterbury Motorsport (UCM) team in New Zealand pushes the boundaries of what can be achieved in racing; in 2016 they overcame their greatest challenge to date. After three years (2013-2015) of competing in the Australasian Formula SAE competition with an internal combustion engine vehicle , the team decided in 2016 to design and build New Zealand’s very first four-wheel drive (4WD) electric vehicle for the competition. The results were remarkable: UCM made history by becoming the first team with an electric vehicle to win a dynamic event at the Australasian Formula SAE competition. Continue reading →
Who was it that said “Nothing in life is free?” Whomever it was, they were wrong. There are a ton of amazing things in life that are free — including our ANSYS Student Version products! Speaking from experience, there has never been a time I have appreciated something free more than when I was a student working my way through college.
In late 2015, we launched our ANSYS Student free download, and since then have released several updated versions. Just recently we made some exciting changes with our new Student Product page boasting two new ANSYS Student Products for Windows x64: ANSYS AIM Student 18 and ANSYS Student 18. Both are now renewable, 12-month product licenses with a shorter and simpler download process. Best of all, we’ve eliminated the need for you to fuss with a separate download key!Continue reading →
