The collection is comprised of measurement and visualisation datasets collected in the FLAIR water channel laboratory. The data relates to fundamental and strategic research projects, the latter done in collaboration with local and international industrial partners. Much of the work is part of international research collaborations with groups in France, USA, China and India. The datasets detail large parameter space campaigns done at high resolution that provide invaluable reference for ongoing research efforts internally and for collaborators for existing and future publications. The collection holds files in raw documented image formats from flow visualisation and particle image velocimetry, and post-processed HDF5 and documented formats; and signal acquisition from laser Doppler velocimetry, force and hot film anemometry measurements, as well as post-processed results.
