Visualization of ice slurries and ice slurry flows.

Résumé

Visualization of ice particles in a rectangular cavity and ice slurry flows in a pipe are performed. The form and size of ice particles is investigated by optical microscopy, which permits a statistical evaluation of the geometrical shapes of the ice crystals. The observed particle densities and the size distributions correspond with the theoretically determined ice fractions. A method applied to measure ice slurry velocity fields is based on ultrasound Doppler echography. The velocity profile, determined by the velocity of ice particles, is measured and several features which are related to Bingham flows are observed. With these experimental results, complete rheograms can be constructed.
