Call: Second Semester
Teaching: Sin Docencia (En Extinción)
Enrolment: No Matriculable (Sólo Planes en Extinción)
The course has the following aims in relation to knowledge and skills to be achieved by the student: i) to know the importance of viscoelasticity and how the strain is modified under shear and extensional stresses; ii) to know the parameters involved in the rheological functions of fluids, particularly in polymer systems; iii) to understand the rehological behaviour of multiphase systems (suspensions, emulsions, polymer mixtures) of chemical, food and cosmetic interest, among others, iv) to know the experimental equipment and advanced hybrid techniques for the determination of structural-rheological processes, and v) to measure experimentally of rheological properties of different kinds of fluids.
The course will combine the mechanical fundamentals with practical applications in the engineering field by means of the study of cases and problems.

Knowledge of the importance in different environments of the rheology (product quality, operation conditions, stability) of mono- and multi-phase systems.
The problems solving, a basic part of the course, require high abstraction capacity of the student.
The practices will allow the knowledge of new techniques and procedures with applications in other technical activities, and also the group work.
Oral presentations will be useful to acquire and practice the oral communication skills.
