Next Generation of SBLI Code

本计画的目的是重新设计一套直接及大涡模拟转捩及紊流的程式。最初的代码是由申请人开发的，用于模拟激波/边界层干扰（SBLI）问题，并已被称为SBLI代码。自其发展以来，该代码已被证明是一个灵活的研究工具，并已被应用于广泛的研究问题，包括亚音速翼型和气动声学。随着几何上更具挑战性的应用和新算法的改进，例如无反射边界条件和湍流的亚网格尺度模型，该代码已分为几个变体。本项目将对代码进行全面的重新设计，目的是增加能力，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，并从正常用户访问中删除。将在代码修改期间编程和使用一套确认用例，其中包括更新当前语言版本并为部分代码纳入版本控制系统。新版本的实用性将通过一个新的国家的最先进的直接数值模拟过渡由于斜激波冲击，包括更多的流动物理比以前的模拟。正式的代码发布将在项目期间进行，并在整个过程中咨询用户。

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.
