6. Special methods
The aim of this chapter is to show that very specific flow visualization problems can be effectively solved by optically performing complex mathematical operations such as gradients, Fourier transforms and Dalembertian transforms.
6.1 Demonstration of optical path gradients in all directions of the plane
To demonstrate unsteady aerodynamic phenomena (coherent structures, turbulence) as a function of time and to validate numerical simulations, a special strioscopic set-up was used
Figure 24 describes the optical system. The essential element is a holographic filter located in the focal plane of the lens L. This filter,...
