Numerical simulations and visualizations developed by researchers from the High Performance and Scientific Computing (HPSC) group led by Dr. Gihan Mudalige at Warwick’s Department of Computer Science in collaboration with Rolls-Royce, PPCU Hungary and Universities of Surrey and Birmingham have been selected as one of the six finalists for the Scientific Visualization and Data Analytics Showcase at the 2022 Supercomputing (SC) Conference, held in Dallas TX. SC is the premier international conference on supercomputing providing a major forum for presenting the highest level of accomplishments in high-performance computing, networking, storage, and analysis. It is held annually in the US and attended by over 10000 attendees from all over the world.

The work present results gained from over three years of developments in the UK EPSRC and Rolls-Royce funded Prosperity Partnership Project (ASiMoV) for developing advanced computational methods for aero engine design. The project aims to develop the world’s first high-fidelity simulation of a complete aero engine during operation, including thermo-mechanics, electromagnetics, and computational fluid dynamics. This is part of an ongoing push towards virtual certification of aero-engine designs.

The visualizations present results from time-accurate URANS simulations of a 4.6B-element full 360-degree model of a production-representative gas turbine engine compressor, the Rig250 at DLR. The mesh size and problem represents a grand challenge problem going beyond the fidelity requirements of virtual certification. The work demonstrates a step-change in simulation capability achieved within a tractable time-to-solution that was previously out of reach under production settings.
