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.
The theoretical contents of the course are teaching based on lectures. The seminars will be employed to solve exercises and case studies by both professor and students. Lab sessions will follow the protocols indicated for each practice and the necessary details for equipment operation and experimental techniques. Operation handbooks of viscometers and rheometer are disposal for the students.
At the start of the course the teaching material (program, schedule, content, problems, lab rules, etc.) is disposal for the students.
Lab practices are mandatory.

Students' learning will be monitored through activities (CB10), works (with oral presentation) (CT4, CG6, CB9) and resolution of problems individually and/or in group (CT5). Lab practices assessment will be from student report (in paper format) and oral defense (CT1, CG7, CG8). The final exam with practical character assesses the corresponding skills to lectures and interactive classes (CE1, CE3, CG1, CB6, CB7).
The only requirement is that the lab practices must be performed and have passed before the exam.
Distribution of the mark (%)
Exam 50%
Works/activities/reports 40%
Tutorials 5%
Professor report 5%
To pass is necessary to achieve 5 points and 3/10 in each part of assessment, excepting Tutorial/Professor report marks.
For second opportunity the accumulative mark of continuous assessment will be maintained.
In additional calls, the student can keep the continuous evaluation marks and no repeat the lab practices in the case of mark high than 5.
This distribution of activities related to assessment will be maintained in the three scenarios.
In cases of fraudulent performance of exercises or exams, the provisions of the Regulations for the assessment of student academic performance and review of marks will be applied.
