Ziel
The objective of the research is the development of an optical technique for three dimensional (3D) flow velocity, size and particle concentration measurements, based on the optical/digital processing of double exposure holographic particle records. Such a technique offers the potential to replace days or weeks of experimental work in fluid dynamics using laser doppler velocimetry by a single day of measurements.
The technique proposed relies on:
a) the isolation within the recorded flow field of a volume small enough so that particles within it travel at nearly equal velocities and on the formation;
b) the later processing, of a diffraction pattern simultaneously representative of particle velocity (three components), size and concentration.
The project is structured in a demonstration stage consisting of:
- the construction of a prototype optical processor along with accompanying computer hardware and software;
- preliminary benchmarking using available, manually processed holograms recorded in conservative conditions;
- the analysis, both theoretical and experimental of the constraints and limitations of the technique;
- a thorough intercomparison of theoretical - experimental findings (iterative if necessary) to establish the criteria and rules for successfully conducting an experiment with regard to future processing; followed by further development to make the system suitable for industrial development.
