Computational fluid dynamics (CFD) has become an integral part of engineering decision-making, providing a deeper understanding of how fluids behave in various scenarios, from the high skies in aerospace all the way to the fast-paced realm of automotive engineering. The task of accurately simulating fluid dynamics, particularly when faced with complex shapes or moving parts, demands innovative ... » read more

Is Liquid Cooling Right For Your Data Center?
By Mark Seymour - 17 Oct, 2024 - Comments: 0

We live in an exciting time—liquid cooling, which once seemed more trouble than it’s worth, is fast becoming an accepted and sought-after technology in the data center industry. That said, it’s still a complex technology to implement, especially in legacy facilities. Is your data center ready to operationalize liquid cooling? Liquid cooling in the data center Liquid cooling in the d... » read more

Powering The Future Of Flight: Designing A Hydrogen-Powered eVTOL
By Caty Fairclough - 08 Aug, 2024 - Comments: 0

A large, bustling city surrounds you — crowded streets and tall buildings reaching toward the sky. You’re late for an appointment. However, instead of hopping into a car, you look above for your ride: an electric vertical takeoff and landing (eVTOL) vehicle. It is a small aircraft that takes off and lands vertically like helicopters, uses sustainable electric propulsion systems, and is inte... » read more

Real-World Applications Of Computational Fluid Dynamics
By Ed Sperling - 05 Aug, 2024 - Comments: 0

More powerful chips are enabling chips to process more data faster, but they're also having a revolutionary impact on how that data can be used. Simulations that used to take days or weeks now can be completed in a matter of hours, and multi-physics simulations that were implausible to even consider are now very much in the realm of what is possible. Parviz Moin, professor of mechanical enginee... » read more

The Journey Of The Olympic Torch: History, Design, And Technology
By Reela Samuel - 01 Aug, 2024 - Comments: 0

The Olympic Torch represents a rich, blended history of ancient traditions and modern values. Bearing the iconic flame, the Olympic torch relay honors the symbolic power of fire, embodying purity, passion, and perseverance. The flame ignites in Olympia, Greece, through the sun's rays—linking the ancient and modern Games—and journeys to the host city, where it illuminates the "Celebration Ca... » read more

How Simulation Addresses Hydrogen Fuel Challenges
By Kiyoung Jung - 18 Jul, 2024 - Comments: 0

By Kiyoung Jung and Kyutae Kim Hydrogen has gained the front seat as a fuel for carbon neutrality. The absence of carbon emission at the point of utilization makes it attractive for net-zero initiatives. Hydrogen fuel possesses qualities like higher flame speed (8x higher), lower ignition energy requirements (15x lower), and wider flammability limit (4% to 70%) compared to typical hydrocar... » read more

Accelerating Speed And Accuracy In Aeroacoustic Predictions
By Veena Parthan - 06 Jun, 2024 - Comments: 0

Simulating aeroacoustics is a tedious task that blends the complexities of fluid dynamics with the nuances of acoustic phenomena. This dual-domain challenge is marked by numerous technical obstacles, ranging from the wide range of scales involved to the subtler distinctions of acoustic signals amidst turbulent flows. To navigate these technical difficulties and advance our understanding of aero... » read more

Digital Twins And AI Acceleration Are Transforming System Design
By Steve Brown - 07 Mar, 2024 - Comments: 0

We are at a global inflection point as we cope with the limitations of energy supply and the consequences of climate change. Regional conflicts are elevating risks in the traditional crude oil supply chain. Changes in rainfall patterns and disputes over water use priorities are limiting hydroelectric power generation. Moreover, extreme weather events have intensified the threat to lives and pro... » read more

Expecting The Unexpected: Analyzing A Data Center Cooling Failure
By Mark Seymour - 15 Feb, 2024 - Comments: 0

Data center thermal management is often a reactive process. Servers issue warning messages, monitoring alarms activate, or employees express concern about general temperature levels/hotspots and then management decides what to do next. For incremental issues, once known, the necessary steps can be taken to resolve or improve these issues; however, what happens when a potential thermal issue onl... » read more
