UK Turbulence Consortium
Lead Research Organisation:
University of Southampton
Department Name: Faculty of Engineering & the Environment
Abstract
An expanded high-performance computing (HPC) consortium is proposed to investigate fundamental aspects of the turbulence problem using numerical simulation. Cases include transitional and fully developed turbulent flows in canonical and complex geometries, with relevance to a wide range of engineering, environmental/geophysical and biological applications. The consortium will serve to coordinate, augment and unify the research efforts of its participants, and to communicate its expertise and findings to an international audience. Most of the staff resource to carry out the scientific work is already in place, funded by EPSRC or other sources, and in all cases the projects have qualified and available staff in place to complete them. This application is for: (a) a core allocation of HPC time to enable consortium members to carry out simulations of world-leading quality, (b) dedicated staff at STFC Daresbury Laboratory and the University of Southampton to ensure efficient use of HPC resources and progress on key projects, (c) a PhD studentship to address issues related to the effect of next-generation HPC architectures on the future of turbulence simulation, (d) travel and subsistence for regular management meetings and international visitors, and (e) support for annual progress reviews, including two expanded workshops to which members of the wider UK turbulence community will be invited.

| Description | Within the UK turbulence consortium, we have been able to investigate turbulence in a wide range of applications, ranging from flow over wings to flow in estuaries and in nasal cavities. New insights have been generated by the numerical experiments conducted that have found their way into modelling. |
| Exploitation Route | Numerical experiments conducted within UKTC have pushed the boundaries of turbulence research. Other groups worldwide are building on work conducted within UKTC. |
| Sectors | Aerospace Defence and Marine Energy Environment |
| Description | A more fundamental study of flow past a Naca 0012 wing tip funded by UKTC has allowed Prof Sherwin's group to assess the capability of LES modelling and the resolution required to obtain mean properties that are comparable with experimental data. This understanding is now being applied to more complex geometries of direct interest to our industrial partner, McLaren Racing Ltd. |

| Title | Incompact3D - CFD code |
| Description | Incompact3d is a powerful numerical tool for academic research. It can combine the versatility of industrial codes with the accuracy of spectral codes. Thank to a very successful project with NAG and HECToR (UK Supercomputing facility), Incompact3d can be used on up to hundreds of thousands computational cores to solve the incompressible Navier-Stokes equations. This high level of parallelisation is achieved thank to a highly scalable 2D decomposition library and a distributed Fast Fourier Transform (FFT) interface. This library is available at http://www.2decomp.org and can be freely used for your own code. |
| Type Of Technology | Software |
| Year Produced | 2013 |
| Open Source License? | Yes |
| Impact | A large (approx 100) number of international users are now using the code. |
