Laboratory of Electrorheology

Course objectives

The course introduces the basic principles of rheology and rheometry, both in rotational and oscillatory regime, with a special emphasis on smart fluid, in particular Electro-Rheological ones. By the end of the course the student will be able to: - Understand and apply mathematical models underlying the flow behavior of both an ideally viscous and visco-elastc fluid; - Differentiate fluids, based on their rheological behavior; - Design and conduct rheometric measurement on materials showing various rheological behavior; - Understand potential applications of smart fluids in industry; - Analyze and interpret experimental tests, based on raw data analysis; - Develop and apply predictive models though software data processing (Matlab).

Exam mode
The final exam aims at assessing the level achieved by the student in the acquisition of knowledge and skills, as described in the training objectives. The evaluation will stem from the examination of two separate tasks: 1) A written report involving the analysis of the topic, the objective, the activity carried out in the laboratory, the results obtained, the discussion of such results, highlighting the personal contribution of the student, in the case of group work; 2) An interview during which the student describes the slides (e.g., a Powerpoint presentation), the contents of the dissertation or of the laboratory report. The exam is scored on a 0-30 scale, based on the quality of the report, presentation and the answers given to the examiner during the interview.
