A team of scientists developed and optimised a concept for wing components that, thanks to electrically driven actuators, are able to adapt their shape as well as their vibratory behaviour during flight. This design considerably improves an aircraft’s aerodynamic performance and reduces fuel consumption. To achieve their remarkable results, the team performed extensive simulations using PRACE supercomputing resources in order to understand and control the turbulence around aircraft wings.
Optimising the shape of aircraft to improve fuel efficiency and reduce the noise they make is a task normally carried out by highly-skilled professionals using high fidelity computational fluid dynamics tools. Swedish start-up Airinnova has been looking to change this, however, using resources provided by the PRACE SHAPE programme to fully automate parts of the optimisation process.
CO2 emissions from the transport sector are increasing, and at this point there are few signs of this trend reversing. Torbjörn Larsson of Creo Dynamics has been running a PRACE project that aimed to iron out some of the issues involved in running HPC simulations that can help improve the design of large vehicles and therefore reduce emissions.
Powering particle accelerators with lasers has the potential to turn what is at present a hugely expensive but vital scientific tool into something far more accessible. Dr Thomas Kluge has been leading a project investigating the crucial phase just before the emission of ultra-intensity laser pulses that are used to accelerate ions.
In a way, superradiance is the ne plus ultra of radiation. Its powerful light is critical for many experiments in a broad range of scientific fields, but it has also been notoriously difficult to generate. Now, with the help of “Piz Daint” at CSCS in Switzerland and PRACE resources, a group of scientists has expanded the concept of superradiance and found a way to more easily generate the valuable radiation. They are calling the novel concept “generalised superradiance”.
Data sent over the internet relies on public key cryptographical systems to remain secure. Paul Zimmermann of INRIA has been leading a project that has been carrying out record computations of integer factorisation and the discrete logarithm problem, the results of which are used as a benchmark for setting the length of the keys needed to keep such systems secure.
The world’s battle against the invisible enemy known as the coronavirus continues on all fronts with HPC making a significant contribution. PRACE has now awarded thirty projects under its Fast Track Call for Proposals to support the mitigation of the impact of the pandemic. The ten referenced in this article will receive 91 712 000 core hours and 350 000 node hours on various world-class systems around Europe.
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.
