Description and contextualization of the subject

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 in applications such as flow around platforms and turbines, etc. 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.

The students will learn the fundamentals concepts and mathematical background of computational fluid dynamics (CFD). They will learn to set-up numerical simulations for aerodynamics applications from scratch 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, aerodynamic forces and performance of a designed geometry
