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.
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.
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.
Researchers at the Nanoscience Center and Faculty of Information Technology in the University of Jyväskylä, Finland, have achieved a significant step forward in predicting atomic structures of hybrid nanoparticles. The work was carried out using supercomputing resources at CSC – IT Center for Science Ltd., Finland and at the Barcelona supercomputing center (BSC), Spain, as a part of a PRACE (Partnership for Advanced Computing in Europe) project.
Cerebrovascular accidents (CVA) are caused by a perturbation in the blood supply of the brain leading to a quick loss of cerebral functions, that is very often lethal. There are two categories of CVA: ischemic CVA (80% cases) resulting from the occlusion of a cerebral artery and haemorrhagic CVA (20% cases) provoked by a bleeding vessel.
Using very high-resolution numerical simulations, astrophysicists at the CEA and CNRS, led by Florent Renaud , have, for the very first time, achieved a detailed analysis of the effects of turbulence generated when two galaxies collide. These numerical simulations, in which the disordered motions of the gas contained in galaxies are seen at extremely small-scale resolutions, at last explain a phenomenon that astrophysicists have observed but which they have been unable to understand until now: that of “starbursts” of star formation when galaxies collide. A process of compressive turbulence helps to explain such starbursts, and why some galaxies form more stars than others. These results are published in Monthly Notices of the Royal Astronomical Society, Letters, May 2014.
