Class Meeting: Tuesdays and Thursdays 10-11.30 pm (Venue: MMCR)

About the course:
Introduction to experimental methods used in mechanics. Fundamentals of flow visualization and quantification, with emphasis on of fluid flow at the micron-scale. Brownian motion and its quantification. Particle image velocimetry (PIV), micro-particle image velocimetry (µ-PIV) and three-component flow measurement in three dimensions. Optical measurement of strain; digital image correlation (DIC). Thermometry at the micron-scale; laser induced fluorescence (LIF). Applications to microfluidic, biomicrofluidic and biomechanics.

Details of course topics:
• Introduction: Introduction to statistical methods (e.g. correlations). General concepts of displacement quantification.
• General concepts on flow visualization: Using dyes, and other visualization techniques to observe flows and flow structures. Introduction to the basics of different optical techniques, such as fluorescence imaging.
• Particle-tracking and Particle-image velocimetry: Fundamentals of particle tracking and particle-image velocimetry (PIV). Details of correlation tracking.
• Microscale flow visualization – Issues and difficulties with microscale flow visualization. How to adopt PIV for micro-scale flow visualization?
• Three-dimensional flow visualization – How to visualize and quantify flow in three-dimensions. Details of two-camera PIV imaging. Aberration based three-dimensional particle tracking velocimetry.
• Strain measurement at the micron-scale – Introduction to digital image correlation (DIC) and related optical methods for strain measurement.
• Thermometry: Measurement of temperature at the micron scale using techniques such as LIF fluorescence will be discussed.

Prerequisites:
Background in fluid mechanics and transport phenomena is encouraged. Knowledge of statistical techniques will be beneficial, but not required.
