Next Generation of SBLI Code

这个项目的目的是重新设计一个直接和大涡模拟过渡和湍流的程序。最初的程序是由申请者开发的，用于模拟激波/边界层干扰(SBLI)问题，现已成为众所周知的SBLI程序。自开发以来，该程序已被证明是一种灵活的研究工具，并已被广泛应用于包括亚音速翼型和气动声学在内的一系列研究问题。随着更多具有几何挑战性的应用程序和新的算法改进，如无反射边界条件和湍流的亚网格尺度模型，代码已分裂为几个变体。本项目将对代码进行全面的重新设计，目的是增加能力并将各种要素重新组合在一起，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移除。将在代码修改期间编写和使用一套验证案例，其中将包括更新当前语文版本，并纳入代码部分的版本控制系统。新版本的实用性将通过一种新的最先进的斜冲击波撞击过渡的直接数值模拟来证明，包括比以前模拟更多的流动物理。正式的代码将在项目期间发布，用户将在整个过程中进行咨询。

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.
