CODE 60369 ACADEMIC YEAR 2018/2019 CREDITS 6 cfu anno 2 INGEGNERIA MECCANICA - ENERGIA E AERONAUTICA 9270 (LM-33) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/06 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester TEACHING MATERIALS AULAWEB 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 Knowledge about modern tools, such as sensitivity analysis, constrained optimization and nonmodal stability analysis, which are useful when analyzing linear systems that evolve in time. The different methods are not only applicable to fluid dynamics problems. A common ingredient to all methods is the efficient computation of sensitivities using so called adjoint equations. The mini projects introduced during the course will give the students the chance to develop, test and document tools which might be useful for future studies. 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. RECOMMENDED READING/BIBLIOGRAPHY Notes and other material will be provided by the instructor and the following textbooks are suggested: Nocedal, J. & Wright, S.J.,1999, "Numerical optimization", Springer Henningson, D.S. & Schmid, P.J., 2001, "Stability and transition in shear flows", Springer LeVeque, R.J.,1998, "Finite Difference Methods for Differential Equations", University of Washington TEACHERS AND EXAM BOARD JAN OSCAR PRALITS Ricevimento: The teacher receives on appointment at DICCA, Via Montallegro 1, hydraulic laboratory, Genoa.
