This research project, in partnership with Andritz Hydro Ltd., aims to develop state of the art computational approaches for the Analysis and Design Optimization of hydraulic Turbines (the ADOpT project), through advancements in simulation and optimization methodologies. The proposed work is divided into two major poles, one that focuses on optimal shape design and the other on steady and unsteady computational fluid dynamics (CFD) analysis. These two principal research themes are supported by a third, complementary theme, on hybrid mesh generation and adaptation. The project will mobilize a team comprising several graduate students and research professionals, working on projects all directly related to the prediction and improvement of hydraulic turbine behavior over a wide range of operating conditions. Close interaction between researchers, students and engineers from Andritz will allow validating simulations through laboratory experiments, and design methodologies through case studies, carried out jointly by Andritz and Polytechnique. As part of the ADOpT project, design and analysis aspects of the distributor, the runner and the draft-tube, the three major parts of a hydraulic turbine, will be addressed. Specific research themes include the development of design space exploration methods, the inclusion of high-fidelity Reynolds-averaged Navier-Stokes (RANS) simulations in a multi-fidelity shape optimization framework, and the validation of unsteady RANS simulations for various off-design operating conditions such as part-load condition, load-rejection and machine start-up. Concrete results expected from this project include the development of advanced numerical methods both for analysis and for design, their inclusion into open-source software such as OpenFOAM for CFD and Nomad for optimization, and their transfer and integration in Andritz' design tools.

该研究项目与 Andritz Hydro Ltd. 合作，旨在通过模拟和优化方法的进步，开发用于水轮机分析和设计优化（ADOpT 项目）的最先进的计算方法。所提出的工作分为两个主要方向，一个侧重于最佳形状设计，另一个侧重于稳态和非稳态计算流体动力学（CFD）分析。这两个主要研究主题得到了第三个互补主题的支持，即混合网格生成和适应。该项目将动员一个由多名研究生和研究专业人员组成的团队，从事与预测和改进水轮机在各种运行条件下的行为直接相关的项目。安德里茨的研究人员、学生和工程师之间的密切互动将允许通过实验室实验验证模拟，并通过安德里茨和理工学院联合开展的案例研究来验证设计方法。 作为 ADOpT 项目的一部分，将解决水轮机三个主要部件——分配器、转轮和尾水管的设计和分析问题。具体研究主题包括设计空间探索方法的开发、在多保真形状优化框架中纳入高保真雷诺平均纳维斯托克斯 (RANS) 模拟以及对各种非设计运行的非稳态 RANS 模拟进行验证部分负载条件、甩负载和机器启动等条件。该项目预期的具体成果包括开发用于分析和设计的先进数值方法，将其纳入开源软件（例如用于 CFD 的 OpenFOAM 和用于优化的 Nomad），以及将其转移和集成到 Andritz 的设计工具中。
