To develop the technologies for 3D Lagrangian particle tracking (LPT) measurements, including calibration and analysis of measurement errors, suitable for turbulence with strong mean flows, which are present in a large number of facilities in EuHIT.
- Development of systems that translate the particle tracking units at the desired mean flow speeds in order to perform Lagrangian measurements. Target research infrastructures: GTF, TTF.
- Development of the automated alignment/focusing/calibration for cameras, data storage/transfer, and illumination subsystems associated with the translation platform. Target research infrastructure: GTF, TTF, BOI, LML, RIMT, CICLoPE.
- Development of calibration and error analyses methods for the Lagrangian measurements performed with the moving platform. Target research infrastructure: GTF, TTF, LML, RIMT, CICLoPE.
- Development of the infrastructure for large-scale Lagrangian measurements: adapting illumination, particle generation, camera alignment and calibration to large-scale flows. Target research infrastructure: GTF, BOI, LML, Coriolis, CICLoPE.
This WP provides the technique to follow fluids (and the particles carried with it) with strong mean flows and hence measure Lagrangian statistics such as acceleration, velocity, relative dispersion, etc.
