Despite decades of research, current climate models still contain a substantial degree of uncertainty that hampers accurate projections of climate change effects such as sea level rise and extreme weather events. Recently, however, climate scientists
Fluid dynamics simulations are a valuable tool for improving the design of aircraft engines and rendering them more efficient. Now, a team of researchers has built the first high-fidelity simulation of a full aircraft engine including several coupled engine components — a milestone that provides insights into the interactions between the individual components and will help to improve future simulations.
The EU’s war against COVID-19 continues and PRACE awarded another ten projects with a total of 227 578 000 core hours under the Fast Track Call for Proposals to support the mitigation of the impact of the pandemic. With the accumulation of knowledge about this novel coronavirus, scientists are discovering new possibilities and tools to exploit its weaknesses and PRACE offers the most powerful supercomputers for their breakthroughs.
Scientists at the Technology University of Denmark have reinvented the design of suspension bridges. Their novel concept not only enables much longer bridge spans but also reduces the amount of building material — and with this the environmental impact of the construction.
In 2014, a team of scientists amazed the world with a simulation of the universe from its birth to the present. Having first confirmed that the cosmological model actually leads to the galaxy distribution that we see in space, the project went on to yield numerous discoveries — for instance about the properties of galaxies and the impact of supermassive black holes on cosmic structures. Still today, the project calculated on PRACE supercomputers inspires ever more new scientific approaches for investigating the origin of our universe.
Cryptic pockets are hidden and appear only when a ligand molecule is actually bound. Now researchers have developed a novel sampling approach, which can detect hidden binding pockets in proteins that were before deemed undruggable. Their approach could even help to battle the current coronavirus pandemic.
PRACE is joining the battle against COVID-19 by providing huge computational power – 195 000 000 core hours – to the first ten projects awarded under the Fast Track Call for Proposals to support the mitigation of the impact of the pandemic. And this is only the beginning.
Shock-related buffeting is a phenomenon that occurs when air passes over the wing of an aeroplane under extreme conditions and can have profound consequences for how wings are engineered and their durability. Professor Neil Sandham of the University of Southampton has been investigating this using direct numerical simulations.
Hydrogen is of more interest than ever as a green power source in transportation. However, the chemical reaction for its industrial production was poorly understood. Scientists have now analysed the reaction in detail to gain insights into a more efficient and cost-effective production.
A doctoral dissertation taking place today at University of Jyväskylä, Finland, shows successful computer simulations that were able to predict the atom-precise structure of a cluster comprising 11 gold atoms. Later, the compound was observed to speed up decomposition of carbon dioxide. In his research M.Sc. Sami Kaappa used computer simulations to study properties of nanosized particles.
