Elements of experimental research and advanced applications of fluid mechanics

Semester 2 · 46049 · PhD Programme in Sustainable Energy and Technologies · 3CP · EN

The students will have the opportunity to improve their knowledge on some specific topics that are generally not treated in depth in basic courses of fluid mechanics, such as turbulence and non-Newtonian fluids, with a special
focus on energy engineering applications. A significant part of the course will be devoted to the explanation and utilization of advanced measuring methods used for fluid mechanics applications in laboratory. In this way the
candidates will acquire the competences necessary in order to design and carry out experimental measures on fluids within their research activity.

Lecturers: Michele Larcher

Teaching Hours: 18
Lab Hours: 12
Mandatory Attendance: Not compulsory

Course Topics
The course will cover the following topics: • Basics of experimental research • Turbulence insights • General features of complex fluids and granular flows • Advanced measuring techniques in fluid mechanics - Experimental methods, e.g. Particle Image Velocimetry (PIV), Particle Tracking Velocimetry (PTV), Laser Doppler Anemometry (LDA). - Experimental instruments - Experimental applications

Teaching format
Lectures, exercises and laboratory activities

Educational objectives
By the end of the course, students are supposed to be able to: - Knowledge and understanding: explain the main principles relevant to the topics addressed in the course; develop an intuitive comprehension. - Applying knowledge and understanding: give examples of real applications and practical problems to underline how the topics treated in the course are used within scientific and engineering activity. - Making judgements: show the ability to make autonomous judgements in the choice and comparison of the suitable methods and tools for the solution of scientific and engineering problems involving the mechanics of fluids. - Communication skills: communication skills to correctly and properly present the concepts acquired in the course and the analysis of experimental results. - Learning skills: Ability to autonomously extend the knowledge acquired during the study course by reading and understanding scientific and technical documentation.

Assessment
The assessment is based on a discussion on the topics covered within the course and on the presentation of the analysis of the results of the experimental activity.

Evaluation criteria
Students will be evaluated on the base of the discussion of the experimental report. Evaluation is based on a 30 points scale. At the examination, knowledge and understanding of the topic (25%), the attitude at applying knowledge and understanding (20%) and at making judgments (20%), the communication skills (20%) and the learning skills (15%) will be assessed.

Required readings

The topics will be sampled out of different books and scientific publications. Attending regularly the classes and laboratory sessions is highly recommended. Some material will be made available during the lectures through Microsoft Teams
