Data Center Thermal Management Improves
By Karen Heyman - 18 Jul, 2024 - Comments: 0

Thermal issues are plaguing semiconductor design at every level, from chips developed with single-digit nanometer processes to 100,000-square-foot data centers. The underlying cause is too many devices or services that require increasing amounts of power, and too few opportunities for the resulting heat to dissipate. “Everybody wants to try to do more in a small volume of space,” said St... » 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

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

Fuel Economy And Aerodynamics: The Yin And Yang Of Car Design
By Veena Parthan - 01 Feb, 2024 - Comments: 0

From the classic Model T to the iconic American muscle cars, the design of cars has been shaped by many factors over the years. Technological advancements, consumer preferences, and government regulations have all played their part. But one factor that has been a game changer is fuel efficiency. The Corporate Average Fuel Economy (CAFE) standards, introduced in the aftermath of the 1973 oil em... » read more

Can Data Centers Afford To Turn Up The Heat?
By Mark Seymour - 25 Jan, 2024 - Comments: 0

Typically, when we discuss digital twin software for data centers, we highlight how engineers can use data center software to model complex thermals using physics-based simulation and find effective ways to cool IT equipment. However, there are compelling efficiency and cost-saving reasons for data center operators to actively seek to run their data centers hotter. But how can this be done wit... » read more

Understand The Physics Of Re-Entry Vehicles Using Numerical Modeling And Simulation
By Veena Parthan - 12 Oct, 2023 - Comments: 0

In the early years of space exploration, scientists and engineers dreamed of sending vehicles to Mars that could land on the planet's surface and explore its terrain. However, one of their biggest challenges was safely reentering the Martian atmosphere. Many early attempts at Mars missions failed because the vehicles either burned up during re-entry or crashed onto the surface. However, as tech... » read more
