Particle Image Velocimetry: Intro

This lecture provides a general introduction to flow velocity measurements, focusing on particle image velocimetry (PIV). It covers various experimental fluid mechanics techniques such as fan and cup anemometers, pressure-based measurements, and thermal anemometry. The lecture delves into the principles of PIV, including the use of tracer particles, calibration procedures, and cross-correlation analysis. It also discusses the organization of a practical session where students conduct a PIV experiment using everyday ingredients. The session involves setting up a virtual zoom meeting, watching instructional videos, installing PIVlab software, conducting the experiment, and documenting the results in a blog post. The goal is to understand PIV principles and enhance communication skills through scientific writing and visualization.
