Keywords

measurement techniques, data processing, experimental design, sensors

Learning Prerequisites

Important concepts to start the course

Basic understanding in:
- fluid mechanics, thermodynamics, heat and mass transfer
- electrical engineering / electronics
- numerical data analysis and processing

Learning Outcomes

By the end of the course, the student must be able to:

• Carry out an experimental modal analysis of a real structure, S4
• Characterize experimentally the steady-state or dynamic response of solids, fluids S11
• Quantify the temperature, pressure, flow and composition of a fluid E24
• Describe the technics used to measure physical flow quantities; choose the appropriate technic to measure to a desired accuracy AH24

Transversal skills

• Set objectives and design an action plan to reach those objectives.
• Use a work methodology appropriate to the task.
• Demonstrate a capacity for creativity.
• Continue to work through difficulties or initial failure to find optimal solutions.
• Write a scientific or technical report.
• Collect data.

Teaching methods

The physical background and working principles of various measurement techniques will be taught through video lecture by various lecturers. This knowledge will then be put into practice in the form of independent group projects. Students will be guided through the process of designing and conducting a reliable and repeatable engineering experiment and will learn how to use different measurement techniques. Support will be provided by teaching assistants during practice sessions.

Assessment methods

Final written exam (30%)
Scientific and technical report (70%)

Supervision

Office hours	Yes
Assistants	Yes
