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
(CN02) Acquire advanced knowledge and demonstrate, in a context of scientific and technological research or highly specialization, a detailed and well-founded understanding of the theoretical, practical aspects and work methodology in one or more fields of study of Chemical Engineering .
competence
(CP02) Conceptualize engineering models, apply innovative methods in problem solving and appropriate computer applications for the design, simulation, optimization and control of processes and systems.
Skills
(HD04) Search, process, analyze and synthesize, critically, information from various sources to establish the corresponding conclusions.
(HD09) Address problems from a scientific perspective, recognizing the importance of finding and managing existing information.
The lectures will be developed orally, with the support of digital presentations. The interactive classes corresponding to the resolution of practical problems will be developed on a blackboard in the classroom, paying great attention to the speed and pace of presentation and interaction with the students, highlighting the scientific and technical aspects, both in relation to calculation and applications. The lab sessions will be carried out following the protocol established previously of each practice and with the greatest possible detail regarding the handling of equipment and experimental techniques. Viscometric and rheological measurement equipment has basic operating manuals available to students.
On the first day of class, all the necessary teaching material will be available to students (subject program, subject contents, problem bulletin, assignments, practice scripts, etc.) on the course of campus virtual.
Attendance at practices is mandatory.

Student learning will be monitored through activities (CN02), work (including presentation in class) (CN02, HD09) or solving problem individually and/or in groups (CP02, HD04). The lab practices will be graded based on the evaluation of the practices report and their oral defense (CP02, HD04). Students will also take a problem-solving exam (CN02, CP02, HD09).
The only requirement is that the practices have been carried out and passed before the exam. Any grade obtained during the course and evaluable in the first opportunity of each call, will be kept, if applicable, in the second opportunity.
Assessment Distribution
exam 50%
Tasks/activities/practice reports 40%
Tutorials 5%
Teacher report 5%
Student learning will be monitored by completing problems and activities individually and/or in groups. In addition, students will take a problem-solving exam that, together with the laboratory report, will allow them to individualize the final grade.
To pass it is necessary to obtain at least a total of 5 points and 3/10 in each of the parts of the evaluation, except in the Tutorials/teacher's report sections.
In the recovery opportunity, the accumulated score of the continuous evaluation is maintained.
In additional calls, the student will be able to use the grades from the continuous evaluation and if the practices are not suspended, they will not have to repeat them.
In cases of fraudulent completion of exercises or tests, the regulations for evaluating students' academic performance and reviewing grades will apply.
