Challenge​

Reducing emissions is an increasingly important factor for aircraft manufacturers, whether through aspirations to reduce environmental damage or due to tightening EU and US regulations. Many companies also put emphasis on design for noise reduction, driven by customer desire and noise pollution concerns. Obtaining accurate estimates of aerodynamic forces is key to understanding and tackling both issues. Computational Fluid Dynamics (CFD) is an important design tool for the aerospace industry, used to supplement experimental studies by providing virtual simulations. This means engineers can predict the aerodynamic effects of different aerofoil and fuselage configurations before they turn to physical wind tunnel experiments, saving time and resources. Researchers at the University of Manchester are developing and applying advanced CFD models that represent more accurate physics, better emulating real-life scenarios and offering advantages over ones used in industry. Due to ​greater complexity and number of elements in the models, the
computational requirements exceeded the University of Manchester’s computing cluster. ​

Approach

The research team took their project to the Hartree Centre, home to one of the top 30 most powerful supercomputers in the world. The advanced computation and visualisation facilities enabled them to begin to use their models on full complex geometries, taking the first step toward being able to simulate a full aircraft instead of the “piece by piece” approach previously necessary. ​

Benefits

High performance computing capabilities at the Hartree Centre enabled the team to develop and run models to more reasonable timescales then on their own infrastructure – turnin​g hours into minutes and months into days. The project results were so promising that team has presented its work to industry leaders at a variety of conferences, garnering attention from both Boeing and NASA. Ultimately, the goal is to develop a model that can be used in industry to model aircraft designs more accurately, resulting in greater fuel efficiency, R&D cost-savings and a variety of environmental benefits.​


“To study an entire aircraft using CFD you really need a big computing facility. The Hartree centre’s HPC facilities allow you to use the most advanced CFD models, which on standard HPC facilities may take many months to compute. On the Hartree machines it only takes a matter of days. That speed up is invaluable for academics and industry​.”​
