,Laser-Doppler Velocimetry — Principle and Application to Turbulence Measurements,ow fields can, therefore, be investigated with a very high spatial accuracy. The measuring principle of LDV is based on the physical effect of Mie scattering (s. Chap. 7). Therefore, the flow has to be seeded with particles capable to follow the flow such that their movement reflects the motion of the flow well.

Global experimental information is not sufficient for de­ veloping constitution equations to describe complicated phenomena in fluid dynamics or in transfer

The Schlieren Technique,pler [.,.] in 1864. It is often applied at heat- and mass-transfer phenomena, such as convection, mixing processes of gases or fluids, flame-propagation phenomena, or the investigation of (super-) sonic flows, where the density-gradients of the gas are strong enough for a sufficiently high deviation of the light.

Fundamentals of Holography and Interferometry,plicity of operation and convenience. Holographic interferometry does not require machining or manufacturing of test section windows, mirrors or lenses with special precision or accuracy, because imperfections are automatically balanced by the holographic two step procedure.

Light Scattering,elds valuable information about the scattering matter. A set-up for scattering experiments is shown schematically in Fig. 7.1. Beside the light source and the detectors, also other optical elements, such as mirrors, filters, lenses etc., may have to be placed in the beam path to fulfil the requirements of the specific application.

In special arrangements of the LIF probe, however, pressure and velocity distributions have also been obtained by fluorescence measurements.

Tomographic Measurement and Reconstruction Techniques,ues used in tomography. The mathematical methods implemented in the reconstruction of the measured physical properties are reviewed and the quality of the reconstruction is critically evaluated. Some applications of tomographic techniques are also discussed.
