Various methods of graphics hardware acceleration have been attempted, mixing the pure convolution method with image-based flow visualization.
In Chapter 21 we shall see the importance of flow visualization.
One needs cine-film to learn much from such flow visualization, but the eddies can be seen in Fig. 3.11.
The distinction implied by the first question - transducing versus flow visualization - is not complete.
On the other hand, measurements are often difficult to interpret without the assistance of flow visualization.
The variety of methods of flow visualization is illustrated by the photographs throughout this book.
A cathode made of, or coated with, metallic tellurium releases a dense brown dye, which is effective for flow visualization.
Particle image velocimetry (PIV) is an optical method of flow visualization used in education and research.
Tufting can be considered a technique for flow visualization, used in aeronautics flight testing to study air flow direction, strength, and boundary layer properties.
From flow visualizations (using smoke) around the cowling's leading edge, three salient points may be taken:
