In just about every part of the world, hydro power offers a reliable source for contributing clean and renewable energy to the electricity grid, helping to reduce greenhouse gas emissions. Moreover, sources such as the recent Hydropower Vision report from the U.S. Department of Energy (DOE) predict that significant capacity can be obtained from multiple streams. Further, when assessing the relative influence of specific variables on the potential for hydropower growth, the #1 factor listed among those exerting the greatest influence was “ technology innovation” (in order to increase...
The latest release of Siemens’ STAR-CCM+® software includes several new features to help product development organizations enhance and accelerate their ability to digitally simulate and understand how a product will perform in the real world using the digital twin – a precise virtual model of a product’s physical and performance characteristics. New analysis tools combined with enhanced visual realism enable STAR-CCM+ version 12.02 to help engineers unlock deeper meaning behind complex engineering simulations. Using features such as Adaptive Gridding and the ability to simulate reactions in Solid Oxide Fuel Cells (SOFC), users will be at the forefront of predictive engineering analytics which increases design efficiency, reduces costs and produces higher quality, innovative designs. Developed by Siemens’ product lifecycle management (PLM) software business, STAR-CCM+ is part of the company’s Simcenter™ portfolio, a robust suite of simulation software and test solutions.
Globalization , demographic transformation and climate change are megatrends that will impact the future of mobility. Following this urbanization process, vehicles need to improve in safety, efficiency and range in order to assure economic competitiveness without forgetting environmental sustainability. To support this sustainable development, simulation technologies are fundamental to create efficient electro mobility solutions. This online event will focus on and demonstrate how simulation tools can be efficiently used together as an end-to-end solution, from system down to component level...
Cool is a hard thing to define. It’s completely subjective. But you know it when you see it. There are a lot of ways to present CAE/CFD data. Plots and tables are arguably what we make most of our decisions on. But, “Excel sheets… aren’t everyone’s friend” . Scenes then… you can put a lot of things into your scenes; results on the surfaces of the thing you’re simulating, streamlines that go in and around the thing you’re simulating… These visual abstractions are a deeply ingrained part of our engineering culture. But not everyone has a casual familiarity with this language. People with diverse levels of expertise have to make sense of these abstractions. And those who don’t, or no longer, speak the language daily and who typically have the least amount of time to assemble conclusions, also carry the heaviest decision-making obligations. Maybe some of you are getting ahead of me here, recalling the phrase “Color For Directors,” a phrase I personally find to be demeaning to directors and dismissive of what we do. Cool pictures? Sure, but cool isn’t cool if it isn’t right. I submit that we have an ethical obligation to maintain the fidelity of our data , and taking it a step further, we rely on good fundamental data to make decisions. Now, data alone can’t capture an idea . Effective visualizations (cool is implied here) can capture ideas, quickly and easily, inviting curiosity and engaging broader audiences. In STAR-CCM+® v12.02, you can create photorealistic images and animations, reducing the gap between the time needed for you to communicate your messages and the time needed for others to understand practical implications, quickly placing your information into their own knowledge frameworks.
Using aerodynamics simulation to optimize for pending WLTP requirements
With the shift to improved procedures for fuel consumption and CO2 emissions, a new Worldwide Harmonized Light Vehicle Test Procedure (WLTP) has been developed by the United Nations. The aim of WLTP is to more accurately reflect real-world driving and harmonize emissions testing across the globe. The new testing procedure will begin in 2017 and roll through 2018 in different stages. One key impact of the WLTP is the calculation of fuel consumption/emissions will not just focus on vehicle, engine and transmissions. Engineers will now need to include any special equipment and the weight changes...
We all have seen electric cars on the street. They look very futuristic and demand a second glance from passers-by. And the convenience… you can drive them in the car pool lane, park and even charge it for free in some places. Great! Their price tag is still an impediment to their large adoption by consumers, though, even if incentives exist in many countries. Another reason for their slow expansion is the rather low drive range these vehicles offer. The longest range available on the market is 300 km (a little over 186 miles) in real driving conditions. Although this would be sufficient for the usual daily commute from home to office, people have the feeling this is not enough for the few times a year they’ve got to drive 500 km (over 310 miles), like to go celebrate Grandma’s 90th birthday. Well, we don’t call that selfishness - although we think you should visit Grandma more often - we call this range anxiety, or the fear of being short of gas (or electricity in our case). So that’s 300 km you can do before you have got to spend several hours at the charging station to continue on your journey and be on time for Grandma’s cake. You’d better order a three-course meal, with a long coffee, buy some newspapers and hoover the car to occupy your time while the car is charging. Fortunately, there is a solution to reduce your entertainment bill at the service; it is Fast Charging. If we could charge our EV to full capacity in the same time as we fill our gasoline tanks, range anxiety would not be such a problem. In this blog, we want to explore the complex problem of fast charging with Battery Design StudioTM, understand its implications and see whether there is anything that can be done to remedy this problem.
