Systems and Complex Fluids

Objectives

The objective of the module is to understand the complexity of flows due to:

• rheological properties of the fluid
• interactions with the environment

Four examples are developed:

1. Hydraulic transmission
2. Vibrations under Turbulent flows
3. Porous media
4. Complex Fluids

Description

Hydraulic Transmission: Study of a "Servo-Hydraulic-Actuator"

• Hydraulic Modeling and Control
• Influence of compressibility on performance
• Mechatronic simulation

Vibrations Under Turbulent Flows: Study of aeroelastic interactions (lock-in, flutter)

• Spectral and correlation analysis "real time" vibrations of a flexible structure in a turbulent flow (Welch periodogram)
• Identification of aeroelastic coupling by filtering relations (Wiener-Lee)

Porous media

Complex Fluids
