Proposal for HPCx resources and support for the LESUK_3 Consortium (2006-2008)

本提案是1995年开始的序列中的第三个(LESUK_3)，作为英国大学财团的一项重点倡议的一部分，该倡议旨在以世界级的水平竞争，开发和应用大型涡流模拟方法来解决复杂的工程问题，特别是航空航天。LESUK_3的目的是促进LES技术的加速发展，其中可以产生令人信服的演示，以便学术界和工业界都将认识到LES的好处，并将其应用于未来的航空航天应用。该项目分为多个工作包，在以下两个方面取得平衡：(I)解决基本的大涡模拟算法问题，(Ii)向业界展示通过将开发的大涡模拟方法应用于一系列航空航天应用所取得的进展，如大后掠翼、空腔、翼型和喷流产生的噪声，以及与燃气轮机燃烧室相关的涡流破裂现象。

The present proposal is the 3rd (LESUK_3)in a sequence begun in 1995 as part of a focussed initiative by a consortium of UK Universities to compete at world class level in developing and applying Large Eddy Simulation methods to complex engineering problems, with a particular emphasis on aerospace. The purpose of LESUK_3 is to produce accelerated devlopment of the LES technique where convincing demonstrations may be produced so that both academic and industrial CFD communities will recognise the benefits of LES and adopt this for future aerospace applications. The project is divided into work packages which give a balance between (i) addressing fundamental LES algorithm issues, and (ii) demonstrating to industry the progress achieved by applying the developed LES methods to a range of aerospace application challenges such as highly swept wings, noise generation from cavities, airfoils and jets, and vortex breakdown phenomena relevant to gas-turbine combustors.
