项目摘要
This project aims to re-engineer a code for direct and large eddy simulation of transitional and turbulent flow. The original code was developed by the applicants for simulation of shock-wave/boundary-layer interaction (SBLI) problems and has become known as the SBLI code. Since its development the code has proved to be a flexible research tool and has been applied to a wide range of research problems including subsonic airfoils and aero-acoustics. With more geometrically-challenging applications and new algorithmic improvements, such as non-reflecting boundary conditions and sub-grid scale models for turbulence, the code has split into several variants. The present project will undertake a comprehensive re-engineering of the code, aiming to add capability and bring the various elements back together, while retaining the flexibility of the original code as a research platform. Well-developed code elements will be modularised and removed from normal user access. A suite of validation cases will be programmed and used during the code modification, which will include an update to current language version and incorporation of a version control system for parts of the code. The utility of the new version will be demonstrated by a new state-of-the-art direct numerical simulation of transition due to oblique shock wave impingement, including more flow physics than previous simulations. A formal code release will be made during the project, with users consulted throughout.
本项目旨在重新设计一个代码,用于过渡和湍流的直接和大涡流模拟。最初的代码是由申请者为模拟激波/边界层相互作用(SBLI)问题而开发的,并已被称为SBLI代码。自开发以来,该代码已被证明是一种灵活的研究工具,并已应用于广泛的研究问题,包括亚音速翼型和气动声学。随着更多具有几何挑战性的应用和新的算法改进,例如非反射边界条件和湍流的亚网格尺度模型,代码已经分裂成几个变体。目前的项目将对代码进行全面的重新设计,旨在增加功能并将各种元素重新组合在一起,同时保留原始代码作为研究平台的灵活性。开发良好的代码元素将被模块化,并从正常的用户访问中删除。在代码修改期间,将编写并使用一套验证用例,这将包括对当前语言版本的更新和对部分代码的版本控制系统的合并。新版本的实用性将通过一个新的最先进的斜激波撞击过渡的直接数值模拟来证明,包括比以前的模拟更多的流动物理。正式的代码将在项目期间发布,并在整个过程中咨询用户。
