The teaching methodology will consist of three types of activities:

Lectures in the classroom. In these classes, the lecturer will explain and explain the concepts mentioned above. Exercises related to the subject will also be solved.
Laboratory sessions: these will take place in the experimental fluid mechanics laboratory. These will consist of a theoretical introduction, followed by data collection by the students. Students will then analyse the results, comparing them with the theoretical concepts studied and, finally, they will produce a final individual report on each session.

Practices will be carried out in English, both in the practice script and in the explanation of the practice.

The group tutoring sessions will consist of discussion sessions and sharing of doubts of the students during the development of the work of the subject.
In the multimodal and/or non face-to-face scenario, described below, the teaching staff involved in the teaching reserves the right not to give consent for the capture, publication, retransmission or reproduction of their speech, image, voice and explanations, in the exercise of their teaching duties, within the University of Jaén.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support
