Particle Image Velocimetry [Hardcover]

This book analyses and comprehensively explains the necessary factors for designing and implementing PIV systems that achieve reliable, accurate, and fast measurements.Although the concept of measuring particle displacements is simple in essence, the factors that need to be addressed to design and implement PIV systems that achieve reliable, accurate, and fast measurements and to interpret the results are surprisingly numerous. The aim of this book is to analyze and explain them comprehensively.Although the concept of measuring particle displacements is simple in essence, the factors that need to be addressed to design and implement PIV systems that achieve reliable, accurate, and fast measurements and to interpret the results are surprisingly numerous.

Although the concept of measuring particle displacements is simple in essence, the factors that need to be addressed to design and implement PIV systems that achieve reliable, accurate, and fast measurements and to interpret the results are surprisingly numerous. The aim of this book is to analyze and explain them comprehensively.1. Introduction; 2. Particles; 3. Imaging; 4. Pixelization; 5. PIV systems; 6. Digital image processing; 7. Low image density; 8.
