Members of the UK Turbulence Consortium (UKTC) will present their latest findings at the UKTC workshop 2013, taking place from 9-10 September at Chilworth Manor Hotel, just outside Southampton, as a culmination of five years of funding. UKTC is a group of 27 academics and researchers from across eight UK-based universities, committed to undertaking world-leading turbulence simulation and scientific research. Using national high-performance computing (HPC) resources, such as HECToR, the UKTC investigates fundamental aspects of turbulence using numerical simulations.
‘Despite its crucial importance in many applications, the complex nature of turbulence makes its accurate prediction extremely challenging. This makes the calculations connected to the study of turbulence correspondingly complicated and time-consuming,’ said Richard Sandberg, professor of Fluid Dynamics and Aeroacoustics at the University of Southampton and lead PI for UKTC. ‘Without high-performance computing facilities, such as HECToR, many turbulence problems would just be impossible to address.’
With the awarded computing time, members of the UKTC can perform ‘numerical experiments’ with high-fidelity computational approaches using no (direct numerical simulations) or minimal (large-eddy simulations) turbulence modelling, to answer basic questions regarding the physics and modelling of turbulent flows found across a range of engineering, physiological, and geophysical applications. These simulations will allow members to develop software that will enable new research areas to be tackled with HPC and will help production codes used in the UK capitalise on future HPC architectures, giving UK researchers the opportunity to be the first to explore new physics.
The consortium will also serve as a forum to communicate research and HPC expertise within the UK turbulence community, and to help UK science remain internationally leading in this aspect of HPC-based research.
Professor Sandberg added: ‘The software development projects are essential to maintain the UKTC's worldwide leadership in turbulence research and to provide cutting-edge HPC application software that will deliver internationally leading scientific research on the next national HPC service, ARCHER.’
The Engineering and Physical Sciences Research Council (EPSRC) has just announced further major funding for the UKTC of £11.7m over five years, which will increase the consortium to 31 academic members from 13 institutions. The funding includes around £11 million worth of computing time on UK national supercomputing facilities.
