Do Trees Improve the Near-road Air Quality?

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.

The Australian Formula Collective Designs Winning Race Car Components using ANSYS Simulation Solutions

The University of Western Australia Motorsport team has competed in Formula SAE Australasia since 2001. With the help of ANSYS pervasive engineering simulation solutions, our team has won the event twice, taken the trophy for engineering design four times and collected more than 30 trophies for individual events. As of 2017, we are now partnering with Edith Cowan University Racing, another Western Australian team, in a collaboration known as Australian Formula Collective (AFC).

Getting Power Management Right and Women in Tech

Getting power management right in the era of heterogeneous SoCs is a multi-pronged effort, there’s no getting around it. There are many technical avenues to managing the power in heterogenous SoCs today, as well as a few human ones.

Engineering teams daily try to squeeze more and more power from their designs, which many times includes adding human resources and expertise to the project.

Take an example where a design team leader gets the mandate to include high level synthesis in the design methodology.

Chinook ETS Wind-Powered Car Breaks World Record with the Help of ANSYS

Chinook ETS is a team of student engineers from École de technologie supérieure in Montreal, Canada. We are trying to design and build a prototype wind-powered car with the highest possible efficiency for the Racing Aeolus event held in Den Helder, Netherlands. Our goal is not only to perform well during the race but also to develop efficient wind turbines through numeric simulations, new composites fabrication processes, advanced electronics and out-of-the-box thinking. ANSYS simulation solutions play a key role in our design efforts.chinook team with wind powered car Continue reading

Leveraging Benefits of the Hybrid Cloud for ANSYS Workloads

Engineers at every company are trying to innovate faster while holding down costs. Modeling and engineering simulations are the backbone of these efforts. Engineers may wish to run ANSYS Fluent simulations at scale, or many different permutations simultaneously, that may require more computing resources than are readily available. Hybrid HPC computing combines public and on-premise compute resources to offer organizations a flexible, cost-effective approach to meet these requirements.

How HyperXite Used ANSYS Simulation to Advance in the Hyperloop Competition

The Hyperloop from SpaceX is the future of fast, affordable and sustainable transportation.  HyperXite, our team from the University of California, Irvine, which is competing in the SpaceX Hyperloop Pod Competition, is using ANSYS Fluent and ANSYS Mechanical simulation solutions to design and build a 1:2 scale Hyperloop pod.

If successful, the pod eventually will be able to transport 840 people between Los Angeles and San Francisco at 760 mph while floating on a cushion of air. Of the 120 teams in the competition, we were the only team in the top five at SpaceX design weekend to propose air levitation as our driving force. Continue reading

Student Space Systems Aims High With Liquid Rocket Engine

In 2014, Student Space Systems (SSS) began at the University of Illinois at Urbana-Champaign as a high-powered rocketry group. In those early days, most of the rocket building was done simply with prefabricated parts. Since then, SSS has progressed to designing and creating its own rocket technology, including power electronics, telemetry and propulsion systems. One of its biggest goals — and challenges — has been to create a liquid-fueled rocket engine built with additive manufacturing techniques.

The Need for Speed Drives NASCAR’s Richard Childress Racing to the Cloud

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.

Topology Optimization in ANSYS 18.1 – Motorcycle Component Example

If you’re not familiar with topological or topology optimization, a simple description is that we are using the physics of the problem combined with the finite element computational method to decide what the optimal shape is for a given design space and set of loads and constraints. Typically our goal is to maximize stiffness while reducing weight. We may also be trying to keep maximum stress below a certain value. Frequencies can come into play as well by linking a modal analysis to a topology optimization.

Why is topology optimization important? First, it produces shapes which may be more optimal than we could determine by engineering intuition coupled with trial and error. Second, with the rise of additive manufacturing, it is now much easier and more practical to produce the often complex and organic looking shapes which come out of a topological optimization.

ANSYS Simulation Proves Invaluable to University of Central Florida’s Formula SAE Team

Knights Racing is a Formula SAE team from the University of Central Florida. Formula SAE is an international competition in which students design and build a race car as well as manufacture the car’s components. During the competition, teams are not only assessed based on vehicle performance but in static events like a business case presentation and engineering design review. This year, our team participated in the Formula SAE Michigan competition located at Michigan International Speedway.
