OVERVIEW

The course aims at providing the students with modern instruments to enable shape optimization in fluid dynamics. In the first part of the course different methods are presented, such as Deterministic optimization, Design of Experiment, Response Surface Modelling, Stochastic Optimization and Robust Design Optimization. In the second part the students will learn some industrial open source codes (Dakota and OpenFOAM) and perform shape optimization of realistic cases. The final exam is a project. 

AIMS AND CONTENT

LEARNING OUTCOMES

The objective of the course is to provide students with useful and modern tools to make shape optimization in the field of fluid dynamics. In the first part of the course the theory of the various optimization methods are presented, including deterministic optimization, Design of Experiment (DoE), surface response (RSM), stochastic optimization and robust design. In the second part of the course, practical examples, such as optimization of a wing profile and a convergent / divergent conducts, are analyzed with open source industrial tools (Dakota and OpenFOAM)

TEACHING METHODS

The course will be based on a series of conventional lectures, and numerical examples in relation to respective lecture, for the students to set in practice what they learn

SYLLABUS/CONTENT

The course is roughly divided into three parts; sensitivity analysis, constrained optimization and nonmodal stability analysis. The different lectures include both a theoretical part and practical numerical examples in which the students will put into practice what they learn. In order to facilitate the practical part regarding numerical examples, the initial lectures of the course comprise a short repetition regarding basic numerical analysis. At the beginning of the course the students will choose, together with the lecturer, a topic related to the content of the course that they will study both theoretically and numerically. This "mini" project shall be summarized in a report and finally presented at the end of the course. A sample document regarding the report style will be handed out and discussed in the beginning of the course.
