Toward Quantifying Uncertainties in Large-Scale Simulations of Engineering Flows

Understanding the complex physics of wall-bounded turbulent flows is of utmost importance, considering the presence of this type of flow in various engineering applications. Thus, using high-fidelity approaches such as DNS (Direct Numerical Simulation) and LES (Large Eddy Simulation) has proven advantageous. However, these approaches have at least two main challenges to deal with.

Enabling the future of CFD for safety applications with Exascale systems

On June 11th, 2019, a Norwegian hydrogen refuelling station exploded. The whole hydrogen refueling station network had to be shut down. Toyota and Hyundai are both halting fuel cell sales in Norway. As transportation companies struggle to find the way out of fossil fuels, this event illustrates how safety aspects can become a brutal showstopper.

Enabling the future of CFD for external aerodynamics optimization with exascale systems

Designing the car of the future requires going over the usual RANS approach, since it fails to predict features like transitional flows, instabilities, noise generation, and combustion efficiency with acceptable prediction accuracy. This in turn requires exascale systems to sustain more high-fidelity simulation techniques like LES or DES. EXCELLERAT paves the way to this transition.

Preparing Cloud Physics for Exascale

Cloud model (MONC) is an atmospheric model used throughout the weather and climate community to study clouds and turbulent flows. It’s often coupled with the CASIM microphysics model, which investigates interactions at the millimetre scale. These often model fog, which is very difficult due to the high resolution required – 1 metre instead of 1 kilometre.

New analysis methods facilitate the evaluation of complex engineering data

A further increase in the performance of supercomputers is expected over the next few years. So-called exascale computers will be able to deliver more precise simulations. This leads to considerably more data. Fraunhofer SCAI develops efficient data analysis methods for this purpose, which provide the engineer with detailed insights into the complex technical contexts.

EU-Project helps Engineering SME Improve Competitive Position

Hydro-power plant current design practice is to determine empirically the most suitable design in a series of time-consuming experiments. However, SMEs in this sector have to face private and public tenders to sell their turbines in competitive, fast-paced national and global markets. Zeco’s challenge was therefore to remain competitive by improving their design processes.
