Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

Flow visualization is the process of making the physics of fluid flows (gases, liquids) visible. At the University of Colorado we have a course for mixed teams of engineering and fine arts photography ...

The word “Schlieren” is German, and translates roughly to “streaks”. What is streaky photography, and why might you want to use it in a project? And where did this funny term come from? Think of the ...

Accurately measuring blood flow is critical to the fundamental understanding of cardiovascular disease and clinical decision making. Although researchers have made great strides in computational and ...
