Irakasgaiaren azalpena eta testuingurua

In the framework of renewable energies, the study of the effects of fluid dynamics is crucial for the efficiency and performance when designing a device for energy extraction. The course covers the fundamentals of the theory and numerical simulation of fluid flow, encompassing turbulence effects . The mesh generation process, including goal-oriented adaptive mesh refinement, will also be tackled, since it is an essential and time-consuming component in the design process. Meshless methods will be also discussed.



The students will learn the fundamentals concepts and mathematical background of computational fluid dynamics (CFD). They will learn to set-up numerical simulations for fluid dynamics applications through practical hands-on sessions. They will be able to select the suitable numerical set-up for the different flow conditions. The basic knowledge will be provided for post-processing and evaluating the results in terms of numerical reliability, forces and performance of a designed geometry

Ohiko deialdia: orientazioak eta uko egitea

The student's grade in the subject will be determined by means of the review and assessment of the evaluation tasks proposed throughout the course. The modality of the evaluable tasks consists of:



- the resolution of exercises,

- the development of computer code that solves the problems raised,

- a written report consisting of the description, analysis and conclusions obtained in the resolution of the exercises and in the programming of the computer code and its implementation to solve the proposed cases.



The assessable tasks must be sent to the corresponding link of the egela/moodle platform within the announced deadline.

Ezohiko deialdia: orientazioak eta uko egitea
